Best scenarios/ways to start/run an ongoing campaign?

Hey so my friend and I tried out battletech for the first time last summer- we did a 4v4 skirmish with 2 heavy, 1 medium and 1 light mech each- it was the starter scenario in the beginner box. We both thought it was okay but now we have to itch to play again so I’m wondering if there are any really cool scenarios that are a lot of fun? Or campaigns we can play where we keep the same pilots and upgrade our mechs- something premade like a D&D adventure campaign would be really cool because I’m not confident enough in the rules to make my own and it feels less straightforward than making a d&d adventure which basically boils down to the party going through the dm’s challenges.

Anyways any help or recommendations are super super appreciated!!!
