If I understand this correctly, for proton these personal@, technical@ and so on are aliases (to one principal account).  If I'm correct about that, I think what you are aiming to do actually ought to be done server-side, with sieve or something equivalent.  I don't think the MUA is a good place to be categorizing mail after it's gone to a final delivery mailbox unless you intend to read it and dispose of it somehow.  I don't know what kind of server-side filtering proton offers, so I can't say more about that.

The sidebar shows you things in mailboxes, so as long as the mailbox has the right things in it this is automatic.

You need to use send-hook and send2-hook.  It looks like this in your dotfile (I generally put these into a separate file and then include them in the main dotfile):

send-hook '~f first-address at example.tld$' 'set command-1; set command-2; set command-3'
send2-hook '~f first-address at example.tld$' 'set command-1; set command-2; set command-3'

It is not always the case that the send-hook and send2-hook need to be redundant, but an awful lot of it seems to need that.  Check the manual, but my recollection is that send-hook is processed once when you get into a sending situation whereas send2-hook is processed _after_ you have composed mail and therefore can catch things that send-hook won't.  I have never managed to sort out precisely what is redundant without hours of testing, and I am too lazy.  I think the only penalty is performance.

This works for me with an account-hook, because I have more than one IMAP account in the same session, but I expect that a folder-hook would work the same way.

This is accomplished through the send[2]-hook mentioned above.

I never do this so can't comment.  I leave everything on the imap server.
