Regarding your valid concerns about the PSL, as long as you have a domain already, you can just make a CNAME record to a free dynamic DNS provider's sub-domain record, I've done this for years with a No-IP ddns.net record. I don't especially recommend No-IP as the 30 day verification is a bit annoying, but at < 1 minute of work per month, it's tolerable for a free service and $2.50 a month is an order of magnitude more than what I feel a single dynamic DNS record is worth.
Since I moved to having a pfSense box at home, I'm using Cloudflare for dynamic DNS, no extra fee and works perfectly, but like I said above, probably not available on typical home routers without a regular machine behind the router having to poll your IP to detect needed updates of a dynamic DNS record.
As I was on Namecheap, I was initially going to use their dynamic DNS option, but it turns out it's behind a higher fee to enable full API access to administering your domain, totally stupid, but with their having been bought out by the PE entity I wouldn't want to stay with them anyway.
