I bought my first SSD in 2009. It was my system drive for around 10 years.
When I retired it as my system drive, it still had 90% remaining of its service life.
You don't need to worry about saving write cycles.

SATA SSDs last a long time, yes.
I'd imagine OP is actually talking about NVMe though, which does NOT - or at least not on the scale of old SSDs.
I have put more than a couple NVMes in the ewaste bin over the last few years.
We buy and use them for the performance though - and I for one want the web to feel snappy, so while it could be read/write heavy, no way I'd be moving the cache off my fastest disk.
For stuff like cache (tiny small files frequently read and written to) that’s the ideal thing to store on an SSD over an HDD.
Linux-specific: as of version 147, Firefox respects the XDG base dir specifications, so you should be able to set $XDG_CACHE_HOME.
in about:config
set browser.cache.disk.parent_directory to a HDD folder
Transfer and symlink it?
nice idea,
on a related topic, creating symlink is tedious, is there a way to "move to d disk as symlink folder" to make it easier
Not sure whats easier than ln -s …
