First off Congratulations!!!
Here's my two cents from the places on your list I have tried...
ESPN club is a nice dinner, but I don't know if I would recommend it for your honeymoon. The food is good, and we had a pretty decent server, but I wouldn't think its anything special (its a chain restaurant). If your fiance is really into sports then I'm sure he would appreciate it but again, it's going to be loud (especially if there's a good sports game on). Planet Hollywood I wouldn't do for the same reason, a chain restaurant you can visit other times when not at Disney world
Beaches and Cream is really great, but I would only go there for dessert! The food selection is pretty common and there isn't a lot of seating area in there (if it's busy, you will be sat pretty much on top of other people). I would recommend getting some ice cream to go and walking around the beach club area which is beautiful (especially at night)
I see that a lot of your choices are in the Epcot resort area, and I would HIGHLY recommend looking into Kouzinna. I tried it for the first time in May and all of the food we got was delicious! Our server was great and the ambiance of the restaurant was really beautiful!
I also don't know if I would recommend Biergarten, although I've never eaten there.. the reason I have never eaten there is because you sit family style and will be sat with other families (not that theres anything wrong with that but if your looking for some alone time you may not get to have it when your sitting with other people and their children at your table)... The upside is you might get sat with a great family you can talk to and have a good dinning experience with, but you never know
The Sci-Fi dine in experience is amazing! The set-up of the restaurant is amazing and we had a great server who "stole" my sisters camera and went into the back of the restaurant.. later when we were looking over pictures we had taken, we noticed that the server went into the kitchen and took some pretty funny pictures getting into a "fight" with other servers. However, I wouldn't rate the food here of high quality... It's good, but nothing special
The others I haven't really tried, but I WOULD recommend if your looking for a nice dinner that's not a signature dinning experience to look into Ohana's or Les Chefs De France. I've been to both on multiple occasions (they are two of my favorites). The food at Les Chefs de France is amazing and the location and ambiance is pretty romantic. At Ohana's it might be a little loud depending on if they have entertainment going on, but also you can go watch Wishes on the Polynesian beach after dinner, or just walk around the hotel grounds (which is really romantic at night!)
