Fellow lebgeekers. i think you should do a more extensive research on SSDs. Because some can virtually even have a longer lifespan than an HDD and we are talking about MLC here, which by the way is misinterpreted thanks to the marketing and naming/labeling of certain companies. As MLC has TLC and QLC under its umbrella with the latter having the lowest performance for an SSD once its SLC cache is used up.
What i am trying to say is you are taking things out of proportion regarding the lifespan and performance for an SSD, i recommend (if you haven't) to check the following website
storagereview. There are many more which can actually give you an idea.
Regarding disabling windows paging, you can set it to minimum amount or leave to at automatic as the OS will manage it as needed. Given that most modern OSes recognize the SSD.
It all comes down to the usage but generally speaking you can easily go for a TLC SSD and the price difference is usually for variables like SLC cache, warranty and microcontroller. In any case you will still get the benefit of minimum seek latency and if NVMe interface then things are much better overall.
