One of the trademarks and frankly coolest things about the MCU is that is all connected and characters exist in the same world. Characters have had solo films and dealt with their own issues which I think is good enough. Are you saying you want a Spider Man movie but with no references to the Avengers or other heroes in the MCU? In that regards I think they are heading in that direction given the ending of No Way Home. Black Widow was a good stand alone MCU movie and Moon Knight is pretty disconnected from the overall MCU as well ( for now).
I would wait until the final movie comes out before making judgements about The Guardians involvement in Love and Thunder. It could very well be 5-10 of screen time with them in it ( similar to Iron Man in Spider Man Homecoming or Dr.Strange in No Way Home. Their involvement with Thor in the MCU just stems from his encounters with them in Infinity War and him leaving with them in Endgame. The Guardians have their own third movie coming next year. They also have a Disney Plus Holiday Special coming this year that sets up Guardians 3.
