Homeassistant on raspberri pi5

Helo i was wondering if i could run homeassistant on raspberry pi 5 and other things at the same time, or is it overkill and should i go for raspberry 4?

Am planning to make energy monitor real time watt usage for sensor that has a webinterface, but i want to setup a low power screen with raspberry pi and maybe weather station sensor added in the future too with some other things

So my question is if i can run homeassistant on raspberry pi 5 and other things such as OS simultaneously?

Im thinking of using rasbperry pi's own 7' screen but maybe too much power usage anually??

I also looked at other options such as epaper and hyperpixel, epaper might be too slow with refresh rate and hyperpixel might be too advanced for me. But hyperpixel looks beautiful doe

Anyways pls give advice on what would be best for me as a beginner

Thanks
