Technical room / Router / Access Points / Switches

So - a quick update on my "project": The network cabinet is neatly mounted under my electrical control cabinet. The network cables have already been pulled in - the patch panel has been mounted accordingly - the power strip connected. Only the internet is missing, then we can get started! All purchases, thanks to your advice, make a good impression - so far I am satisfied :) I would like to buy the access points directly at the start (PoE). I can't decide on one - would be happy to get some more input on this. I don't need different networks - no major requirements except: - simple installation - good range - relatively compact (no huge parts) - good wall mounting - not too expensive (up to €120 each) I need 2 in total.

With your switch from the link, the ports are fixedly installed in the switch and the cables are then connected to the ports. The electrician wants a patch panel where the individual ports are modular and can basically be removed from the housing. Then the ports are punched down onto the cable and pushed into the housing from the back. It is just much easier to wire and you have the advantage that you can move the individual ports around in the housing as needed.
Your electrician’s statement definitely makes sense.
