@John_E On your original question, what is “best” is different to your ears than my ears. It is a matter of personal taste. Regarding wattage, I have the same amp you do currently and I’ve never had it near max volume, so I don’t think you need a massive wattage amp for a home setting. From the way you are describing what you want, I think you might want more old school analog/tube, but the digital mimics are pretty solid nowadays. If you wanted to stay with the Fender ecosystem, check out the Rumble Studio 40 or the bigger Rumble Stage 800.
That being said, I agree with @kerushlow that going the computer route can be good if you don’t intend to play out anywhere. However, for me personally, I don’t like being tied to a workstation (yeah, I know technically you can carry your gear around with a laptop, but not what I mean). Sometimes I’m happy to use my DAW, but other times I just want to chill on the couch and play. So for me personally, I have both solutions and then I have the choice.
The other thing worth mentioning is that the Rumble Studio 40 and Rumble Stage 800 are similar to having a DAW in terms of flexibility because they have so much digital modelling. If you combined them with something like a Line 6 HX Stomp or multi-effects pedal then you have tons of choices to find the ideal tone for you, though the amp itself is probably enough unless you want specific effects.
Lastly, I wasn’t sure if you mean you don’t play out of your house ever or if you just don’t bring an amp if you go jam with others. If you aren’t playing with others at all, I’d really encourage you to as this brings a whole other level of enjoyment and satisfaction (assuming you gel with the group). And lucky for us, bass players are the most in demand member of a band. If you want to stay the more solo route, then you can use online collaboration like Bandlab or Soundtrap, but I don’t have much experience with random people on those platforms myself as I play with a local group.
Do your own thing though, that’s just my two cents!
