This knowledge may be useful if we were to rebuild for example an airship (just naming one of your categories for example).
As far as I know, only u-blox is producing their own SoC (albeit for cat-m/nb-iot only) all the others are using existing solutions from Qualcomm and others.
This is only scratching the surface. I did not talk about certification which is another beast altogether.
It's also open source.

not everybody is wired for looking for satisfaction in the job they do. If your hobbies are what fuel you it is ok no to monetize them.
There's plenty of good advice in the comments already. I chimed in just to try taming what looks like an impostor syndrome ;)
Around the house there will be a bunch of sensors connected to the WiFi network, talking via MQTT to a raspberry pi. A few of them will control the heating system.
Temperature and humidity are logged and shown on a nice webpage.
The testing is focused on ZFS but, quoting from the conclusion: If you're looking for raw, unbridled performance it's hard to argue against a properly-tuned pool of ZFS mirrors. RAID10 is the fastest per-disk conventional RAID topology in all metrics, and ZFS mirrors beat it resoundingly—sometimes by an order of magnitude—in every category tested, with the sole exception of 4KiB uncached reads.

Those drivers do work better than their free/open-source counterpart but are hard to install (especially if secure boot is enabled) and do not play nice with the whole GNU/Linux ecosystem.
