The cake-autorate project (https://github.com/lynxthecat/cake-autorate) aims to solve the problem of bufferbloat on varying links speeds - like a 5G cellular connection, Starlink, or even cable modems that get slow in the early evening.

It works by continually monitoring the available capacity and ping time, and increases the CAKE parameters  to the point that there's a bit of added latency, then backs off.

The folks who have added cake-autorate (https://github.com/lynxthecat/cake-autorate/tree/v3.1) to the OpenWrt router (https://openwrt.org/) are having good luck with exactly this scenario.

In fact, they have a specific config file for Starlink - https://github.com/lynxthecat/cake-autorate/blob/master/Example_Starlink_config.sh to use as a starting point.
