But there really isn’t much advantage to paying the monthly subscription, since most items are for rent or sale.

That is a misunderstanding about what Apple TV+ actually is. The items for Buy or Rent are from the iTunes Store, and not part of the subscription.

One glitch I noticed right away was that when I would pause a show or movie to go do something fir several minutes, it would revert back to the main menu and have no memory of where I left off, causing me to start all over and manually fast forward to where I was. It also doesn’t remember where you left off between different devices. The app doesn’t seem to be able to update like all the other subscription services do.

That is supposed to be controlled through iCloud, but Apple needs to be allowed to log what you have watched to do so. See privacy settings.

Another is I cannot access the Apple TV app on my LG tv in my bedroom to watch the movies I have purchased on Apple TV already.

Not all models LG TV support the Apple TV app. You have to be specific. Apple TV app-supported smart TVs - Apple Support
