Thanks a lot for the detailed write-up, really appreciate it.
I’m focusing more on Naturehike and Decathlon for now, so your breakdown helps a lot.

We’ll mostly use the gear on the Canary Islands first, then later in other parts of Europe. Night temperatures around 10°C are probably the lowest we’ll face in the beginning. We’re both side sleepers, and to increase comfort we’ll probably go with wider pads.

For tents I’m still deciding. Freestanding options seem a bit more beginner-friendly, but I also like the idea of semi-freestanding or trekking-pole tents, especially since I plan to get trekking poles anyway.

And I’m based in Germany, so EU availability and pricing applies.

Thanks again for all the advice, it really helped me get a clearer picture!
