Libby's canned pumpkin is actually a C. moschata squash (Dickinson). There are quite a few bush type winter squash. Gold Nugget is a small Hubbard type (C. maxima) Burpees Butterbush is a small butternut (C. moschata) and there are a number of C. pepo types (mostly acorns and delicatas) The Cheyenne Bush Pumpkin actually has a short 6 foot vine But is compact with 6- 10 lb orange traditional pumpkins (C. pepo). It is a 1943 release- a cross between New England Pie and Cocozelle. Bushkin is a newer variety but similar in size and plant growth. Supposed to have better flavor than Cheyenne, but I have not grown it.
Don't grow celery so can't help with that.
