It really depends on what you personally like using and what works best to control the lights the way you envision as a lighting designer. In terms of being able to do more with a console versus an interface, I personally feel the opposite is true. In general, interfaces offer substantially more capability over an equally-priced hardware console. Usually, interfaces are more powerful than consoles costing tens time that!
For instance, you'll probably find that as you shop around most hardware consoles costing under $500 are more or less the same thing coming in 2 scene preset or budget moving light console flavor, some larger or smaller than others depending on your needs. You don't really get into serious options until the 4K price range and most professional light consoles cost more than most cars! Seeing as this is for your bedroom, I'll wager that you're not willing to spend that kind of cash on such a desk! Now, while I'm not saying an interface is always the way to go, interfaces give you features such as sweeps, palettes, command prompts, true cue stacks, and other features simply not seen on budget desks.
In terms of which one is easier to control, they're all their own animal from my experience. I've sat down at both hardware desks and software consoles with no clue what I'm doing, and then gotten in front of something I'm more familiar with and been right at home. You just have to practice. Some manufacturers and models follow more of an 'industry standard' way of doing things while other take their own approach, but so as long as you don't plan on renting your board or having other professionals use it you won't have to worry about that. Find something that feels natural to you. You are the one that's going to be paying for it and using it after all!
The big question is what lights do you want to control and what do you plan to really do with them? How expandable of a system do you want and do you ever plan to graduate from your bedroom?
Hope this helps!
