You don’t need to have long addresses, you should be using hostnames and domains anyway. Ipv6 addresses are often simpler than ipv4 ones. E.g. prefix::1 for your router. Prefix::2 for the next device, and so on to Prefix::FFFF for the first 65k machines if you wish to set it up that way. Ipv4 exclusively on your lan ruins my day because I have to maintain servers and software to support users that only use ipv4 and flat out refuse ipv6 connectivity - it’s expensive and takes a lot of effort to maintain dual stack support.
Most of the time I do use hostnames, but it doesn’t matter what I use as a user if I have a list of addresses I have to look through in log files, or enter addresses for configuration or whatever. My brain works on IPv4. I’m sorry for ruining your day, but I assume, or at least hope, that you get paid for the work. I do not and I have more important and pressing things to do than learn IPv6 and reconfigure my whole network.
