jarvis VS FlorisBoard

I didn't last long with the stock keyboard before installing AnySoftKeyboard which is one of the few FOSS alternative with support for swipe typing. The experience was... OK. It felt slow and it's accuracy left a lot to be desired. I still had to be slow and pretty accurate, so it didn't really feel like much of a change from the stock experience. FlorisBoard have also introduced their own implementation but the feedback I read suggested it would be much the same as my experience with AnySoftKeyboard's gesture typing.

Keyboard → OpenBoard (OpenBoard Upadted Fork, FlorisBoard when the v4 will be released...)

You could try https://github.com/florisboard/florisboard, available on F-droid.

I am excited to see how this project will develop. I'm sure starting out with https://florisboard.org/ was extremely helpful. Other devs have started from scratch, but florisboard is already advanced and feature rich. You could keep it open source to alleviate concerns of privacy. Just an idea.

The Github code repository (https://github.com/florisboard/florisboard) had an update on February 24, so the app is not abandoned. It reads like they plan a massive update for the next version, and word suggestions will be available.

I tested two: AnySoftKeyboard, it's stable and works even on very old devices, but it lacks modern features and the settings are really ugly and confusing (but once you look at all of them, you'll be able to make the keyboard the way you like it, is very customizable). And I also tested FlorisBoard, it's modern, beautiful, but it's a work in progress currently in early-beta stage and it has many incomplete or buggy features. So I ended up with AnySoftKeyboard. I know there are others, but it was these two projects that caught my attention the most.

Probably only via AOSP mirror. It's an AOSP component so not officially available as its own component. Check out https://github.com/florisboard/florisboard for a GitHub based OSS keyboard.

FlorisBoard (perhaps): This one is the dark horse for me. It's layout etc can be all customized to my liking and it's FOSS. But it doesn't have a suggestion provider API etc none of that yet (WIP) so, as it stands now it's "just" a highly customizable FOSS "keyboard" app, and nothing more. I have high hopes for it though.
