True. Depending on how heavily they compressed it to fit between those studs it will likely be less than R13. No matter whether you use fiberglass or rockwool, you should make sure you buy insulation sized to the depth of the cavity it will insulate. Then use an insulation knife to cut in for obstacles within the cavities.
Theres a baseline cost for work to be done, the OP decided to build an 8x10, but easily could cost a similar amount or a few thousand more for a shed 4x larger.
HVAC techs are in such high demand, they can charge exorbitant rates to install/service, that its not in their interest to service them, or even install them.
It took me a while to find a company to install a mini split I purchased on my own, and I paid $$ for labor. This was only because I didn't have the time.
That said, mini splits are so cheap (sub $500) that its easier to just purchase a new one than repair.

I hate being a broken record, but batteries are $100/kWh now, sometimes less. Don't buy proprietary. You can get a 3kW inverter and 5kWh of battery for ~800 USD. Want more storage or output? Just add batteries or swap out the inverter.
I do 't mean playing video games but lots of things could be done within the power range of the device.
For example be able to use the ssh access or synchronization web app from wifi, be able to use basic web page, synchronize with your own server like ftp server, ...
All that kind of things not very complicated or requiring power. And I'm not even asking for the work/app to be done by remarkable but that the interface to do that is available.
A few things could be done by connecting in ssh and replacing the xserver but it is extremely clunky and could easy make your expensive tablet a brick. But it shows the kind of things that would be nice to be done with it.
I guess that a simple code editor/visualiser could easily be done.
I posted in a comment above that I (well Codex) was able to get full Chromium running on it. It’s not fast by any means but is usable if you just want to read a web page on e-ink… so it’s not crazy underpowered
