After lots of thinking I think I'm going to try to get the A7III with 55mm f/1.8 Zeiss and the 90mm f/2.8 Macro..
I like the Zeiss for walkaround and ive liked the color and rendition ive seen from it, its also a good wider option for the corgis and actually might work better for a group shot (its sometimes honestly easier to just shoot loose and crop...)
The Macro because i do a lot of macro shooting and i just dont trust converting my 100L over, i use AF for macro frequently (Read, almost always/constantly) It will double im hoping for portraits of the corgis as well. Plus FoV wise its wider than the 100L is and its the same as the 45mm f/2.8 Macro-Elmarit i used to have on the GX8. I've heard the 90mm Sony isnt a slouch at focusing either, especially on the A7III/A9 despite being a macro lens, and f/2.8 on Full Frame is equal to f/2 on my 50mm Sigmalux which is where i usually shoot it when im doing portraits of Luna.
The 85mm f/1.8 is awesome, but also cheapish and easier to get the money together to add later
