LTSC also doesn't get incremental updates other than absolutely critical vulnerability fixes. It's specifically meant for machines that need everything to function exactly the same over a long period of time, e.g. point of sale machines, the accounting/inventory machine that hangs out in the back office, so on. You aren't going to get any major update or overhaul pushed to an LTSC version of Windows.
LTSC can also be a pain in the tuchus to get your hands on as an individual. If you have an MSDN account however (like through work or school) they often come with a bunch of keys for Microsoft products, including LTSC products. You can check here, just try logging in with your work/school email - even if it's non-Microsoft - and see what happens.
If you can't get your hands on an LTSC copy, then at a minimum try getting a copy of Windows 10/11 "N", which comes without Windows Media Player and Skype pre-installed. It's nowhere near as clean as LTSC, but every little bit helps.
