After trying to find a camera that will suffice to my interest in shooting, it appears to me that an SLR with one lens will be the best way.
From landscape to sports and portrait.
I have both Sony and canon. I’ve chosen to keep the canon 6D with the 70-200 2.8 IS.
I will be selling my a6000 white body with the 85mm 1.8 and 24-70 f/4 in the summer sometime. They work best in my black/white street shots. Thanks folks

Four different photography genres that call for different camera and lens setups.
Landscape... what will you be doing with the images? Large prints? If so, a high megapixel large sensor camera like Fuji's 100MP would be ideal. But maybe not very practical. Staying within the Canon ecosystem, either the 5DS/5DS-R (50MP) or the R5 mirrorless (45MP) would be a good choice, with the right lenses. The R5 also can shoot sports, but the 5DS/5DS-R would be a poor choice for that. Both cameras would be good for portraiture, but neither would be my choice for street photography where a small, inconspicuous camera is usually preferred.
For sports there is some advantage to using an APS-C camera. The "teleconverter effect" of the smaller sensor allows much smaller, lighter less expensive lenses to be used. My 300mm f/4 lens costs under $1500 and weighs less than 3 lb. and "acts like 500mm" would on full frame. I can hand hold that lens all day long. In comparison, my 500mm f/4 lens cost over $9000, weighs over 7 lb. and is not hand holdable for more than a few minutes. Another example, your 70-200mm f/2.8 on an APS-C camera will act almost like a much bigger, heavier, more expensive 300mm f/2.8 would on full frame. So while the image quality and low light shooting capabilities of a bigger sensor might be nice to have, if we want the same "reach" with a full frame camera, we have to haul around much bigger, heavier, more expensive lenses!
It might be possible to use a full frame camera in crop mode, to get the same effect. But to do so you need a high megapixel FF camera. An APS-C crop is roughly 40% of full frame. So a 45MP or 50MP camera will be reduced to approx. 18MP or 20MP APS-C. That's not bad (Canon 7D Mark II is 20MP. All current Nikon APS-C are 21MP). However, lower MP full frame camera simply lose too much with a crop... a 30MP camera like 5D Mk IV would end up around 12MP, while a 26MP 6D will be reduced to only about 10MP. (Note: The APS-C crop might be done in camera... or possibly better, in post processing. Doing the latter allows the shooter more control over the final crop.)
For sports and other action photography (wildlife, birding) it is also desirable for a camera to have a fast frame rate and a high performance AF system. The 5DS/5DS-R cameras are relatively slow shooters at only 5 frames/sec. Not good, though it's AF system is up to the task (as good as any DSLR). The R5 would be a much better choice, with 12 frames/sec mechanical shutter (20 frames/sec electronic shutter, but that risks rolling shutter effects). The R5 also has a much more advanced AF system, with face and even eye recognition, as well as highly reliable tracking capabilities across almost the entire image area.
BUT, even better for sports might be Canon 90D DSLR or Canon R7 mirrorless. These APS-C cameras both have fast frame rates, plenty of pixels (30.5MP), and highly capable AF systems. Between the two, the R7 mirrorless is the more advanced, with an AF system comparable to or even better than the R5's. It also has 50% faster frame rate with it's mechanical shutter. Its in-body image stabilization (IBIS) and some other features would also be useful.
While a full frame camera might be preferable for landscape, the 30.5MP sensors in these two APS-C is more resolution than a lot of full frame cameras offer. For street photography, all these cameras... 90D, R7, R5 and 5D Mark IV... are pretty similar in size and weight. However, the lenses for the two APS-C cameras can be much smaller. There are even "pancakes" such as the RF 16mm or EF-S 24mm and EF 40mm that can make them almost "pocketable" (umm, you'll need big pockets :sm16
.
A possible drawback to both the APS-C cameras... for some reason Canon didn't design them for use with a battery grip and doesn't offer a grip for either the 90D or the R7. This is unfortunate for sports shooters like me who use grips during long shooting sessions to help avoid having to pause to change batteries at inconvenient times. There are likely to be 3rd party grips for them, though they don't interface as fully with the camera as an OEM grip would. There ARE grips available for both the R5 and 5DIV. (Note: I deliberately chose cameras with removable battery grips, so that I could lighten my load when I wanted, such as when taking a hike with my gear. I appreciate, but don't use the "pro" bodies with built in grip, like the 1DX series and R3.)
Weighing all the options in the Canon ecosystem right now, it were me wanting one camera to do landscape, sports, portrait and street photography... my choice would be the R7. It's not "perfect" for all those purposes... but to me it's better than the alternatives. The lenses used upon it are another very important factor. I would NEVER limit myself to just one lens. The whole point of an interchangeable lens camera is ability to adapt it for different purposes... telephoto for sports, wide angle for landscapes, one or two large aperture primes for portraiture, and one or more very compact lenses for street photography.
What I actually do is have different lenses AND different cameras for different purposes: a pair of 7D Mark II for sports, an older full frame for the occasional architecture/landscape/seascape, and a very compact mirrorless with a few lenses for street photography. I'm prepared to do portraits and macro with any of them. I never take all the gear out on a shoot. I select what I'll need for that day's work or play. Sometimes when there are multiple possibilities, I'll put some extra stuff in the car... just in case.
