Yeah, the Fender Rumble series makes a nice baseline. There’s nothing really special about them, but they sound good and are inexpensive.
The Rumble Studio (basically like the normal amp but with built-in effects) is a cute upgrade from the normal Rumble as well - it’s not optimal to have all your effects tied to a specific amp, but it certainly doesn’t hurt the amp to have them there on the amp either. I could also see using amp/cab sims on the amp (and likely reverb) even with a normal pedalboard or multi-effector. I’d personally prefer a normal amp and external effects, but if you want it all on the combo, then that seems a good path.
Which brings us to the Roland cubes. I have never heard one in real life myself but I know people seem to like them. They also have built-in effects, and are relatively pricey. $240 for a 20W amp is pretty steep, and that’s the cheap one. You can get a Rumble 40 V3 for about the same price new. On the other hand Roland makes really high quality stuff.
Still, given the price, I would suggest going with a Fender or Orange and buying the effects separately if you want.
Last suggestion, buy used
