You can still get play store apps, if you must, on a de-googled phone using Aurora Store. You can bypass the safetynet attestation as well with some methods (used by things like banking apps). I've been using a google-free phone for a month now and after switching I reinstalled the apps I used the most (mostly through F-Droid), and then I created a separate profile solely for installing apps from Google Play (still through Aurora Store). It works well for me, I haven't had a single issue. Maybe because I really only get 3-4 apps from Google Play, the rest is F-Droid.
