It's always worth it to run the latest OS, after the initial dust settles. Whether it is worth it to OP or not seems more personal. I gained either performance or feature improvements, or both, from w7 to w8, then w10, and now w11.
However, long ago, I maxed out the mobo/cpu (static part) with ram and SSD as these are obtainable and easy to upgrade. At this point, with these items maxed out, whatever OS is on there will be humming much better than before. If you periodically rebuild the OS and debloat it, so much the better. I'm over 5 years or more on my current ASUS mobo/cpu combination, and I've been able to install all these OS's on it.
Don't know if OP is at max ram and on SSD, but if he were, and as he is already running w10, he'd gain a few more percentage points of performance and some feature gains just from w11. If he isn't maxed out in ram and SSD, then that's where I'd go first.
Of course, a more modern mobo, cpu, ram, & SSD set will always make a difference ... the chipset changes with each mobo/cpu. Is what you have doing it for you, or do you need/want more (performance, features)?
I would tend to run the latest OS platform, and on some cycle of years, upgrade to the latest mobo/cpu/ram/ssd hardware platform to get the latest chipset gains. Rarely does one drive the other, as my current platform ran or is running from w7 to w11. You don't really *need* the latest hardware to run w11, if you google a bit, but it might be a "good for the economy" thing if they make you think it is required.
I did change out my nvidia graphics card separately over the years, as that gave me a boost in certain areas ... cad, gaming, video production, and such.
Hope this helps ...
