I don't know how many people you are hosting but a rule of thumb is 1-1.5 lbs per person which includes leftovers. No matter how many people are coming to my home I always opt to cook a 9 lber instead of larger birds since I'm sure it'll fit in any of my ovens (I have a convection "nuker" as well as a range) and cooking pans. Sometimes I need to roast up to 3 small turkeys but since I can spread that out over a few days it's fine.
Sometimes I buy fresh, sometimes I buy frozen. Depends on cost and availability. I try to avoid birds with that useless red pop up thermometer in it and those that are pre brined like the classic Butterball and kosher birds. Been brining birds for a good 20+ years so prefer my own.
Since I almost always wet brine and air dry (air drying gives crispier skin) the birds I'm assured they will be moist.
The only time I don't brine the bird is when I'm making Julia and Jacques deconstructed turkey with stuffing. This is a bit of a project so I won't even detail the how tos here, LOL.
Here is a universal chart for meat brining. Very simple when you follow the directions.:

I generally add whatever kind of seasoning I want to the brine...simplest is citrus and thyme:

Oh and if you don't have an adequate roasting pan a baking sheet that looks like this is fine:

I haven't used a turkey baster in decades since discovering that cheesecloth draped over the breast and soaked in the liquid of your choice (wine? Champagne? apple cider? melted butter mixed with chicky broth? You choose) did the job quite nicely with minimal oven opening or burnt wrists, LOL. Be sure to remove the cheesecloth in the final hour to brown the breast meat.
If you've an electric carving knife now is the time to pull it it. You can carve a bird up without it looking like mice have been gnawing at it beforehand. First I cut
half the breast off starting at the keel bone in one hunk. Then the other side of the breast. Slice the meat on the diagonal in easily to eat pieces....about 1/4" thick. Next tackle the thigh and drumstick. Push the leg up and to the side as if the turkey was doing leg lifts and cut straight through the joint. Now slice the meat off the bone in whatever manner makes you happy. Major bones and joints out the way you are free to cut the delectable meat under the bird.
I parade the whole bird around the table so all can see the beauty a la Norman Rockwell and then retire to the kitchen to slice it up returned on a platter easy to serve.
Finally (and sorry this is a bit out of order) I make sure my sensor thermometer has up to date batteries. Set the probe in the breast, choose a temperature (generally 150-155 F), 30-60 minutes of foil tenting and I'm done and so is the bird.
HTH, good eats and trust me you don't need to be the person who forgot to defrost the bird until the day, and grumbled when your Mom and elder sister hacked the thawing bird to death in an effort to get it into the oven faster....this would have been my first time hosting if only I admitted it was me......
