Deep packet inspection is unlikely the culprit in my experience. SSH and SFTP use port 22 by default which is probably blocked. I log in to my work VPN through common ports 80 and 443 on public WiFi.

You could also have your back end pull from a git repo every minute. A cron job could check a GitLab repo for changes and update the site if any changes are found.
That is a networking issue which is not specific to Hugo. You need to solve this as most of the suggestions also involve SSH.
One way is to use a VPN like openvpn or wireguard that can use a common port like 80 or 443.
What do you find limited about Hugo?
The ability to edit titles seems like an obvious feature that Reddit never added.
Many apps that are on F-Droid are also on Google Play, but there are exceptions. Gadgetbridge (smart watch connection app) warns that the Google Play version is unofficial and unaffiliated. An unofficial app might be upstream compiled without modifications, but this opens users to potential supply chain attacks from the uploader and Google.
This is the first top-level comment that hints at the main criticism against systemd. systemd is increasingly difficult to replace as time goes on. I like and use systemd because it has a fast boot, but I wish the project was developed in a more modular way that had choice built-in. It is instead developed as the way that everyone should systemd instead of alternatives. This philosophy gets in the way of distributions that want to provide alternatives (Devuan, Gentoo, Parabola, etc.). Some of the sysadmins I work with closely use Devuan and follow development. I hear the patch set around bypassing systemd grows in size and complexity each year which is worrisome for choice.
The moral of the story is to support projects that you might want to use in the future even if they are not finished yet before you need them. Mastodon and Lemmy have been around for years. When the mainstream alternative suddenly becomes lame, it isn't an emergency on the devs part.
You can apply this to most alternatives. Support GIMP, Krita, and Inkscape if you are an artist using Adobe products. Support mixxx, audacity, and lmms if you are a DJ. Support LibreOffice if you use Microsoft Office.
Sometimes I think I'm not even good enough to have impostor syndrome.
Or you're trudging uphill and will eventually plummet to your death.
Markdown with neovim for gits.
LibreOffice for spreadsheets and presentations.
LaTeX for publications and moderncv template for resume.
Etherpad for collaboration.
DD might be using something like that. I have heard they block TOR as well. I have used a VPN with ports 80 and 443 on their WiFi years ago.
