I think you're right in thinking that you'll need more than one type of nappy for different occasions.
Have nursery already said that they'll use cloth nappies? Just that some are reluctant - I don't know why though, it's no more work for them. I think the easiest for nursery to master would be pre-stuffed stuffables (fuzzis, minkis etc), then there's no extra work involved vs disposables. Fuzzis are my favourites as they dry VERY quickly, and if you use microfibre inserts, they dry v quickly too. We did have a shortish period tho' when they used to leak, but DD did go through a very chunky thigh stage at the same time. I never tried any other stuffables, but some swear by happy heinys for better overall fit.
After Fuzzis my next best favourites are Ella's House hemp nappies because they're nice and slim and v absorbant. They do however take FOREVER to dry and go a bit stiff if they're not dried in an airing cupboard or tumble drier (we have the latter, but I hate using it too, seems to defeat the object)
Tots Bots are great because they're so absorbant but I don't really like them because they're so huge and I struggled to get clothes to fit over them. When DD was chubby they made her look HUGE. Now she's skinny and they just look, well, odd. And they take ages to dry too. I thought I'd hate the hassle of nippas, but they make the nappy fit better than velcro. A lot of people use Tots at night because they're so absorbant (I never used cloth at night just Nature Babies disposables, DDs nappies are always HUGE in the morning)
Rainbow Bots are slightly better as they're thinner (and so less absorbant) but I still think they're too big. Might be OK with boys' clothes though??
I have quite a few Motherease onesize which are pretty good, not too bulky, and should last til potty training unless you're likely to have whopper babies. DD is v tall, but they still fit fine. They have pop in inserts which you don't need to use at 1st. They're reasonably quick drying (but not as fast as Fuzzis).
If you go for 2-part ones, then the BEST wraps are definitely the motherease ones - the popper ones (airflow?) are best, but the velcro ones are OK too. Another reason I like Fuzzis, you don't have to faff with wraps.
I'm by no means a cloth expert, I got a lot of good advice from the babycentre.co.uk cloth nappy forum, also twinkleontheweb.co.uk and kittykins.co.uk.
HTH, or I may have just confused you more!
