Don't expose your services directly to the internet. Instead rent a VPS and the use Wireguard to bring the traffic back home. In your home network your services should be in there own VLAN and everything should be isolated and sandboxed. Everything has the potential to be compromised so always practice least privilege and defense in depth.

You can pay for dyndns service which should be more reliable than free ones. I don't have any experience with those, so I can't give any recommendations. What I'm running is that I use few of the free ones which are updated either from my router or from a linux VM and I've just pointed few easy to remember CNAME records from my own domain to those dynamic addresses. It's not the best thing in the world, but my dynamic IP tends to be pretty static as it usually changes only when my own hardware is down for a longer period of time (few hours or so, so a longer power outage or a hardware maintenance gone wrong).
I use TailScale and their free Personal plan.
Disclaimer though: I haven't done much due diligence on it. It was easy to install when I first started self hosting with Umbrel and I use it so rarely that it's good enough for my usage.

If you can avoid it, don’t open ports in your firewall, don’t publish your home IP address, and keep everything behind a VPN. If only you and your family will be using these services, go with Tailscale or one of its competitors. Otherwise, VPS or cloudflare tunnel/competitor.
