Just bought a used TUF-AX5400 for cheap which was on 3.0.0.4.386_50224. I jumped straight to this one in one go. Did a factory reset before and after flashing.

I use it as a media bridge only, so far so good.

Seems like your router is supported by AsusMerlin, an alternative firmware that extends the router's features, should you need it.
