I can personally really recommend the fly e3 pro v3. It’s well priced and is a 32 bit board that comes with both an stm32 and a esp32 built in allowing you to run duet reprap firmware without a spare raspberry pi thanks to an amazing port. Since it’s reprap firmware you get all the advantages of klipper like web gui, input shaper, editing config files without recompiling etc but without having a spare and quite expensive raspberry just lying around. https://s.click.aliexpress.com/e/_DCEqwdT
Because I use programs that only work well on windows, for example Solidworks
