No. If you care about owning games, don't rely on subscriptions. The main purpose of PS plus is for online, not so you can abuse access to 'free games'. If you're not consistently using the multiplayer, you shouldn't have a sub.
I finally cancelled my PS Plus a couple years ago, and the only game I really played that was tied to it was MLB The Show 2019. I just ended up buying the game this year, and even though I got a physical copy the console immediately recognised the game data and asked if I wanted to transfer it all to the physical version. Didn't have to re-install or anything, very painless and simple.
