Hi y’all, thanks for the help with my question yesterday. I did a bit of homework, and I think I’ve got things figured out. Here’s my revised plan:

configure a cron job to update DuckDNS with my IP address every 5 minutes
use ufw to block all incoming traffic, except to ports 80 and 443, to allow incoming traffic to reach Caddy
configure the Caddyfile to direct traffic from my DuckDNS subdomain to Jellyfin’s port

Does this seem right this time? Am I missing anything, or unnecessarily adding steps? Thanks in advance, I’ll get the hang of all this someday!

do not use default ports 80/443.

In my opinion, you'd be fine using default ports. Guess there's no harm in using other ports though, other than the pain of having the remember which port to use if you ever forget when adding a new device, etc.

Edit: I should add that im speaking of only ports 80/443 here. If you must expose ssh over the internet (probably shouldnt) for example, then yes, use a non-standard port (I use non standard ports for pretty much all apps except http/s).
