Although a lot of guys don't care for using the bucket, I do...works quite well too!
So, I'd suggest using the bucket for the first year and see how things go.
I used a rear blade for several years (150' drive). They do OK, but I had no other use for the blade so I sold it. If you have other tasks for a blade, it might be worth picking one up.
How one uses that rear blade is important. Those lower arms aren't built for pushing and there are no trip springs on a rear blade. Using the concave side of a blade can dig into your drive, so make sure any blade you buy can rotate 180 degrees. I'd also consider adding skid shoes, especially if you want to use the concave side.
The first year or two I used my rear blade, I did push with it. After that, I drove over the snow rather then push. With judicious use of the rockshaft lever, I could minimize any damage or digging in by the blade.
Now, as far as your dealer's suggestions, my choice would be the FEL mounted front blade. Adding $2K to the price of the tractor isn't too bad.
As others wrote, front snow blowers are very expensive and are limited to one tractor model (note, the 59" front blower Deere sells can be used on various Deeres...it's different brackets used between models....so, you can use a front mounted blower on different Deeres....but if you buy another brand tractor, it won't work).
BTW, this year I'll be using a UTV mounted plow and let the tractor take a break...
