Are there no better digital stabilization algorithms? This seems like it could be fixed in post processing on your phone/cloud.

there absolutely are, without a gimbal, by using a somewhat large sensor and movement/orientation/inertia sensor ICs to perform a software crop and stabilization as the video is recorded.

such as the hypersmooth 2.0 or hypersmooth 3.0 on a gopro hero9 black/hero10 etc. but those are considerably more expensive cameras.

search youtube for gopro hypersmooth 3.0 and you'll see some examples of the same gopro with and without hypersmooth turned on.

A recent, but really good, open source one is https://gyroflow.xyz/ . There's also Reelsteady, Hyperflow etc..

I've used Mercalli to fix this in post-processing but it's not a simple fix.

This is caused by a non-global shutter so you have to spend a lot of processing power to fix it.
