On some devices I run custom distributions (mostly LineageOS), others I just root and de-fang by removing all objectionable content including the Google bits. In all cases I put on F-Droid with a few configured repos to get the applications I want. On a few devices I also add some proprietary apps which are more or less mandatory - electronic ID (BankID) being the main one - either by manually installing it or through Aurora Store, an alternative play store front-end which does not require a Google account. No Google, no problem and no real hassle. My current main phone - a Xiaomi Redmi Note 5 Pro - is 8 years old, I already have a replacement in a drawer but have not configured it yet because I first want to make a cover for it. Even though it is 8 years old it works fine, the battery holds for 2 days and all applications I need still run on it. The oldest device in use is 15 years old and also works fine but it can no longer be used as a phone since 3G was switched off where I live.
