I kinda have a niche/weird view on keyboards; I use the default aosp keyboard firewalled for no internet access and with spell check turned off. I find it annoying when it changes what I say, and if Idk how to spell something I look it up and try to remember it for next time. I have typos here and there but mostly I don't mind and I feel it makes me more deliberate in my use of language.

There are also plenty of open source and generally privacy-respecting keyboards on FDroid like Urik keyboard, so no compromise is needed imo
