Previously*, I wrangled QGis version 3.28 or better on Raspberry Pi's trying to complete pertinent tutorial lessons and hitting local software application limits. I had success with OpenSUSE and FreeBSD (on x86 hardware). My next focus was NetBSD on a Pi4 (with the full 8GB), after upgrading the package system (in fits and starts) to the Q3 2023 release.

Summing up:

QGIS 3.28.7-Firenze 'Firenze' (exported)
1. Clicking on the table on the right side lights up the areas on the left. Huzzah. Tiny sliver of badly-drawn border there as I could not (did not) locate the "fix overlaps" routine). Next lesson.

The attributes link is a huge step in correlating pictures to numbers, as it were.
2. Filter on the far left (funnel icon) where I selected by a routine just 2 subsets. Heads above manually clicking to select, and saved for future changes.

3. A tree view of attributes rather than a grid view,

The lessons worked, as far as an academic follow-the-book exercise went. I knew the parts I skipped or didn't complete, learning enough to see applicability to a few real-world projects.
The export to a georeferenced PDF is almost there but the NetBSD packages I installed omitted a GDAL subset.
Back to the package manual. And the mailing support lists with a reasonable question.
Next lesson: Elevations with topographic or other sources, or a dive into database storage/retrieval.
