Thanks for the suggestion. It supports multi-lingual typing which in a requirement for me. I haven't checked other keyboards for a long time so perhaps that has become more common.
I don't find the multilingual features as polished as Gboard, this is what prevents me from switching, in Gboard you can install multiple languages and write without having to switch and it will provide autosuggestions and spelling support based on the language you're typing without having to manually change the language
I recommended FUTO keyboard in sibling comment. FlorisBoard is a nice FOSS option, but some features are still WIP. Personally, I've switched fully to ThumbKey, but that's got quite a learning curve.
It's not nothing, but it's something. And, at least on my phone, it's not obvious if it can be turned off.
