Haha on all points. They may be smarter than us in the end here....
Good points on what future owners might think of your setup/wiring etc. 90+% of buyers probably have no idea.
I rewired 99% of my house myself; including a lot of cat5e cabling (was the best cable available in the day) wherever I could route it. I had an electrician friend who spotted me on the permits/inspection paperwork. He did a pre-inspection of everything I did, then chastised me for it being 'too neat'. He told me to pull some staples here and there, and 'slop up the nice straight wiring runs', or the township/electrical inspectors will know its wasn't a licensed job. 
I didn't fool the final inspector, he said 'real nice job on your wiring'; he couldn't find anything wrong with it as he winked.. and signed off on it.
I havehad multiple contractors/people doing work at the house that make a point to tell my wife how great the wiring/breaker box is. That perplexes my wife. She's like "they're just wires...". ??
Back to this topic, I dhcp reserve 90% of my connections; I've got an OCD reservation assignment map that lets me know VLAN, location, function etc, just from the address.
I run open source OpenWrt on my router; I love the software and its constant updates and full flexibility; all my configs are scripted so I can easily upgrade/restore/factory reset/restore my setup. I've got more than 64 reservations... probably less than 128, but they are stored in the flash file system as Jeff notes; I'm not aware of any limitation (other than blowing out your flash map),
The router hardware, even though longer in the tooth (linksys wrt1900acs) has great routing performance for my needs; I have long since shutdown the embedded wifi radios on the router.
I got two ubiquity wifi6 lite APs to upgrade the radios and hang off the linksys router; and I put the ubiquity (free) open controller server on a raspi (for AP config and setup); Ubiquity updates the server software on a regular basis. The server software and AP firmware are very well done (especially for AP roaming/handoffs between the APs).
I haven't used the ubiquity router/server hardware/software to comment; yeah its pricey. Many people say its worth it.
