FS have inexpensive switching and SFPs. Even if you get another brand switch I still recommend FS SFPs which can be ordered for compatibility with various vendor equipment.
Yes the one I linked was 100W / 20V / 5A
For power delivery you need a cable rated for it. Cables can have the same USB specification but different power limits.
Typically to charge a Laptop you want a cable rated for 60W power delivery or higher. I would just go with 100W rated cable as the price is reasonable.
The recordsize used is dynamic up to a maximum of the zfs recordsize property. See https://klarasystems.com/articles/tuning-recordsize-in-openzfs/
The purpose of tuning it is about optimising reads and writes within files larger than the recordsize. For example if you have a database that typically stores its data in a single large file then because it is a large file zfs will be reading and writing it in recordsize chunks on disk. If your databse operates on 4k size changes then reading and writing 1MB at a time in disk is a waste of I/O bandwidth.

Recordsize sets the maximum it can be for a file.
Either leave it at the zfs default of 128k or since your use case involves primarily reads of large files you could set it to 1MB.
Your network traffic will not go through the new probe IP.
The static route just ensures the probes to that IP use the correct WAN link. Mainly covers the case where there are multiple WAN links and the probe needs to use a specific one.
I was just going to play it for the rewards... was still playing an hour after the reward popped.
A neat game. It took a bit of thinking to beat it at Level 7.
