How do you use your labels, folders and filters to organise your ProtonMail inbox/archive?

I decided to get Proton Unlimited yesterday and I've been trying to organise my emails, but I feel like I have the tendency to accidentally use folders and labels for the same thing so I end up with similarly named labels and folders (oops!), so I'm curious to see how people here organise their mailbox.

I was thinking one folder per alias/account/website, but when I try to add filters I'm reaching that filter limit where I have to wait 24 hours. I tried the sieve filters but, although I'm a decent programmer, it doesn't feel super intuitive.
