The "variable" fileset handling is a pain in the ***. Especially during
restore.

Why do you need to keep it as minimal as possible? The first step I'll do
for this number of clients is to generate required configuration with
automation scripts, especially that you have an easy file directory pattern
to backup. No manual config file crafting.

So what do you want to achieve during restore?
I think your solution is invalid to your requirements.
To generate a "dynamic" fileset you can use:
- Any name preceded by an at-sign (@) is assumed to be the name of a
file, which contains a list of files each preceded by a “File =”. The named
file is read once when the configuration file is parsed during the Director
startup.
- Any name beginning with a vertical bar (|) is assumed to be the name
of a program. This program will be executed on the Director's machine at
the time the Job starts.
- If the vertical bar (|) in front of File= is preceded by a backslash
as in \|, the program will be executed on the Client's machine instead of
on the Director's machine.
- Any file-list item preceded by a less-than sign (<) will be taken to
be a file. This file will be read on the Director's machine (see below for
doing it on the Client machine) at the time the Job starts, and the data
will be assumed to be a list of directories or files, one per line, to be
included.
- If you precede the less-than sign (<) with a backslash as in \<, the
file-list will be read on the Client machine instead of on the Director's
machine.
You can find examples at Bacula's manual -
https://www.bacula.org/11.0.x-manuals/en/main/Configuring_Director.html#SECTION002170
This should allow you to achieve what you want exactly with some external
scripting which will dynamically prepare what directories/files to backup
at the selected job.
But, when you change a fileset to switch from one year to another then
Bacula will mark all "missing" files as nonexistent/deleted for the next
job. If this is exactly what you want then great! Or I totally
misunderstood your requirements, then sorry.
