Layer 3 for Bitcoin. Would be very sexy to get this on umbrel seeing how a node hosting competitor already has them (Voltage)

OpenHab for smart homes. https://www.openhab.org
Some basic file management and transfer tools. Trying to get terrabytes of data into the Nextcloud instance is exhausting. sftp tool would be nice to directly upload bulk to Nextcloud and then have those files be accessible by PhotoPrism, Jellyfish, File Manager, etc.

I think FullNode Services that store the Blockchain for Litecoin and Monero would be a really great addition to the umbrel app store.
Monero node
WebtThings Gateway
It’s much more intuitive than Home Assistant.
There is a community store app now! GitHub - deverickapollo/umbrel-monero
