Yes the unverified apps thing will affect you no matter what. It’s not getting better any time soon. There are a lot of reasons for that.
You can’t “de-google” if you are 100% married to googles navigation service. It’s gonna become much harder to avoid play services (the google play store and all its telemetry) if you need a banking app and teams even if they seem to work now because the “reasons” above.
Other people have said that “privacy is a spectrum” in response to the following unconventional advice, and that’s true! Your conception of privacy may simply be getting away from the default apps and keeping the play store! Just keep that in mind:
If you’re actually gonna do any of the things we consider phone stuff on your phone, in terms of privacy and security it goes graphene > appropriately configured ios > a big gap > everything else.
Maybe consider switching. There isn’t a big cost difference anymore.
Speaking from experience with both android and ios platfoms including many custom roms and the alternative repos/app stores, it’s much, much easier to stay as private and secure as possible on ios.

Micro form factor corporate “desktops” are the easy and cheap answer here. More expensive but also easy are the n100 lil boxes. You may need to disable or cover a bunch of gamer leds.
Weirdly cheap but with one hidden cost is appletv 4k, you gotta either pay monthly or one time to the infuse (jellyfin client) app developer to unlock dolby decoding. TBH I don’t mind paying one time for software, it’s the subscriptions that bug me also it’s what we still use so that’s why it makes the list.
After all the stuff about super/bad box started getting around I haven’t been able to really trust android set tops, which sucks because the price is right on those little fuckers.
Also I often found awful support environments for safely using android tv boxes, lack of lockable bootloaders, undocumented memory for blowing the original install back in, weird variants of weird socs.
It made me do the Seinfeld at the movies gif, ymmv.
