Geographic Information Systems

I want to set GeoServer in a machine that will also be hosting a webpage (a web map) and a database (PostgreSQL with PostGIS). Map layers will be stored in the DB, published in Geoserver and served to the Web.

I'm between Fedora Server and Ubuntu Server, I use Fedora Workstation as my daily drive, so I feel more leaned to Fedora Server. However I'm still new in the field and this will be my first time setting up a Server, so maybe Ubuntu has more documentation and thus more easy.

Any suggestion?

I'm curious if anyone else has experience with tools for editing and collecting data in the field.

I'm vaguely aware of QField for QGIS. I believe ESRI has their own tools for that context, but I don't know what they are.

I'm also familiar with some tools for a specific industry: namely inspection and data collection for utilities. Some of the ones I know are probably best described as "long in the tooth."

What are the options these days? Where do you go for users that need to collect data in the field, whether it's inspection data, correcting existing GIS data, or collecting new data?
