F-droid is safer than the playstore.
Yup, the irony.

It's already done. There is LineageOS. I use it on an old tablet that can't go above Android 5 on the factory OS. This way it can get as high as 7.1 with LineageOS 14. Still old, but new enough to run the handful of apps I'm using.
Some more recent devices of course support (are supported with) releases based on more recent Android. LineageOS 23 is based on Android 16. The problem is, you have to choose your phone specifically to run the alternative OS. Not everything is supported and even those that are, opening the bootloader can be a pain in the ass. Like with my old Nokia 7 Plus.
You can find unofficial builds for officially unsupported devices on xdaforums, but they can have issues or you might lose features. I tested one with an SM-T280 tablet and had a lot of stability issues and didn't handle the camera well.
There is also GrapheneOS, but device support is even more limited. Exclusively Pixel phones. CalyxOS that only support a handful of devices besides Pixels. There are also some smaller forks mostly not worth bothering with.
Problem is, for some apps these forks fail device integrity check and won't launch. Also, installing these forks are not as trivial as wiping windows and installing Linux in its place.
Something I have no experience with, it the Chinese forks like Xiaomi HyperOS. These were born out of necessity after Google started to block them from using official Android.
Now consider you want the smaller phone, with dimensions like from over 10 years ago. Mission impossible. I wanted something newer for compatibility with few apps that I find handy as Android 7 is getting left behind. Though on the compatibility, I do wonder if some would work if you just decompiled APK and changed minimum SDK value. I've seen one app with changelog mentioning smaller corrections in two instances, where minimum Android version was bumped at the same time. But in my case, Android 7 was already a bit too much for internal storage of old Xperia E3, always low on space.
I settled on Unihertz (Chinese brand) Jelly Max, but, they're not a role model, impossible to make proper custom OS for their phones because they don't publish sources. And GSIs may not have all working hardware functions. This phone has notification LED that presumably depends on custom programming to work right, not like on older phones where apps could adjust LED behavior for themselves. There's also FM radio and IR blaster. All these are rarity these days.
I didn't find Android slow for general usage, though my impression these days is that it needs more memory than Windows 11.
I'd like to replace Google Play Services with microG at some point. I suspect they're significant factor when it comes to battery utilization. But, every time I read into it, I have doubts about the whole procedure and back out.
