I don’t think I’ve ever had a canned or jarred sauce that was even close in taste to even the most basic homemade version.

I don't think OP was referring to jarred sauces, rather home-made sauces made using canned (tinned) tomatoes, as opposed to fresh.

The majority of Italian tomato-based sauces call for canned tomatoes.

Canned whole tomatoes used in recipes are not comparable in any way to canned or jarred premade tomato sauce.
