Thumb-Key is aiming to be an FOSS replacement to the now unmaintained MessageEase. Like MessageEase, it offers a 3x3 touch-and-swipe layout. Such a layout takes some time to learn, but allows to type fast and accurately, thus getting rid of the dependence on prediction/auto-correction, without which QWERTY on small touchscreens would be unusable. Some people report being able to type > 50 WPM on MessageEase and the same should be possible with Thumb-Key. It's a young project and is still missing many features and gestures of MessageEase, but it is active and has a community here at thumbkey@lemmy.ml.

I only recently switched from GBoard to MessageEase and ThumbKey, and I still around 25 WPM, but I found that I stopped making mistakes when typing out the long master password for my password manage on my phone, because this is one of the areas where auto-correct couldn't help.

But I am still far away from reaching the speeds of swiping on a QWERTY-keyboard without word prediction. So if you don't mind that and don't want to spend your free time learning alternative layouts, stick to QWERTY layouts, but if you want a keyboard layout to type exactly what you want, try one of these 3x3 boards. To be honest, if you want to give it a shot, out of the two I wound probably still recommend MessageEase, as Thumb-Key is very alpha, but that might change. I have both with the same layout and switch back and forth.

Definitely Florisboard as it has the most features and best theming support but I was using AnySoftKeyboard in the past and it's okay too.

I am using OpenBoard as well. There even is a fork with gesture typing for the adventurous.

Florisboard. It has glide-typing, and I found it to be better than AnySoftKeyboard. Main downside is it doesn't have next-word suggestions yet, but that's planned for the next major release.

I use the slide-to-type feature a lot, and currently the only other keyboard I found with this feature is anysoftkeyboard, but it is (or at least it was the last time I tried) sadly so much worse than gboard, so I'm still using Gboard currently

Openboard

I used to use Florisboard for a while, but the lack of autocorrect (however annoying it may be sometimes) made me switch to AnySoftKeyboard. I mostly like that I can customize away all the unnecessary emoji and single use buttons (e.g. .com button when filing in links), as the usable space on a phone screen in portrait mode is already cramped.

Happy with it so far, but mobile phone keyboards (outside of physical ones), are generally still a bit of a pain IMO.

AnySoftKeyboard

Hacker's Keyboard. The only keyboard I'll ever use on Android.

Simple Keyboard

Edit: Actually switched to FlorisBoard after reading this thread. The swipe is mostly accurate so far. Hoping it improves in the 0.4 release!

Used OpenBoard, but switched to Florisboard because OpenBoard seems abandoned and the developer of FlorisBoard came back with an update of what he's working on. So far I'm not mad, the lack of autocorrect did make my typing much better. But as a dyslectic person I can't wait for proper autocorrect to be implemented.
