I’ve been using the FUTO keyboard for a couple of months after Florisboard was driving me nuts with the typos (I refuse to accept that I have fat thumbs and dislexia). So far it’s a huge improvement. It does take a while to ‘learn’ to change to the correct words when I hit space, and I’m always choosing the right word (when I remember to, lol) to improve the suggestions over time. Also, I had to get some good dictionaries for it. I liked Swiftkey a lot, but I not willing to bend over to the surveillance, so in my opinion, this is the best FOSS option I could find.
