I have the Multiling keyboard. I don’t recommend it to others as it’s rather long in the tooth and still has quirks I haven’t fully sorted. I keep it precisely because it does multi-language support with separate dictionaries; I switch it between U.S. English and French Canadian and autocorrect follows. It’s massively customizable but I don’t understand it and am more likely to render it unusable than to make it better.
