I understand that semi-hollow electric guitars have a different weight and tone. I also know they can more easily cause feedback in some situations (though not a factor for me).
Those are the main reasons to buy a semi-hollow guitar in general, so no, there are no other reasons - except sort of one recent reason for a specific brand - see below the line.
I'd say the main goal in buying your first guitar is twofold: Price and preference. You want a guitar that you just like for some reason. That will help you enjoy the difficult early stages of learning. And it doesn't make sense to spend a lot of money on your first guitar. The most affordable guitars are almost entirely solid body electric guitars.
I recommend solid body electric guitars from companies like Fender to all of my beginning students because the affordable Fender guitars are wonderful instruments with great feel and tone at very low prices, and an electric guitar has some advantages for beginners over acoustic guitars. My students who are more interested in acoustic guitars I recommend go with that instinct, but anyone who wants to play rock music in general and doesn't have a strong preference for acoustic, I recommend starts with electric.
(The following information is as of February 2018) Gibson has put their Memphis factory, where they have been making all of their US-made semi-hollow guitars (AKA their "ES" line) for a long time, up for sale. That means there will likely come a time in the nearish future when Gibson will no longer be making those guitars on the exact same line that they have for decades. Does that even matter? Maybe not. Probably not. But if you have long wanted a Gibson ES guitar for their particular tone and feel, and you don't want to buy a used one or you don't want to risk the prices on Memphis made ones going up, now might be a better time to buy one than next year. Of course, it might be that Gibson declares bankruptcy in July and never makes guitars again, or they reorganize and by 2020 are making the best guitars they've ever made for much better prices than today. So it's pretty much a gamble. If you want the "historicity" of the Memphis factory, now would be a good time. Since you're a beginner, this is probably not an appropriate choice for you, as these guitars start around USD 2800 in price and go up rapidly from there.
