FWIW I think you're good to go, that's fine (there are no "bad" Voigtlander/ Zeiss lenses on this platform or probably at all and Brian here recommends the TTA 75mm which is endorsement enough as far as I'm concerned).
This is exciting, trust me! But the more you use the camera, the more the 28mm and 90mm focal lengths will eventually gnaw away at you, especially the 28mm as annoyingly for me I saw that in RF terms they are
not similar to 35mm lenses.
Anyway, you may as well get a couple of LTM adapters now as this is definitely all part of the fun (you *will* end up getting LTM lenses, don't think adapting that AI glass will prevent this) and any of the Canon LTM 50mm lenses (F1.8/F1.4) from a performance/ value perspective is an excellent way to go IMHO.
I mention Canon LTM lenses but the (second hand) choice and availability from other brands is vast. It's all very well if one buys new gear because a lot of it renders all the same subject to a lot of PP and if you like that then that's great. But that's not the case here as, again annoyingly, these old 50mms have their own identity and render differently. You may like the results, you may not, but if you do you'll find that many of these lenses can be had for cheap which justifies purchases (more than one btw) and thus puts your wallet in danger. So there is a skill to containing GAS in this respect which you have to develop.
And finally, there can be frustrations to owning a RF camera and lenses - the secret is to learn to enjoy them

. IMO it's well worth it.
Just my 2 cents.
