From my limited experience, you’re going to want to be in a Battlecruiser at the smallest. Even in C1 WHs they rats can be pretty tough. A Hurricane would probably do well but I went for Gnosis, largely because of the huge cargo hold. Plenty of room to stick in a mobile tractor unit and a mobile depot, along with any optional mods and plenty of ammo. The MTU with salvage drones makes looting the sites easy as pie. I haven’t got a fit to hand but I think the Gnosis is a very customizable ship so play to your strengths! I made sure I could manage lvl 3 missions easily before I went for it. Learn your WH catagories as anything above a C2 may be too much for a battlecruiser! Weekends are a bad idea! II made about 100 mil clearing out a C1 but that may the top end.
Good Luck and fly safe o7
