I agree with all of these suggestions: https://www.floretflowers.com/an-update-on-fall-bulbs/

Avoid Brecks! And all the random places owned by the same company.

I would recommend any of the daffodils other than the ones primarily grown for forcing. Some will spread more, but all will be long lived. Your big King Alfred types will eventually make glorious swaths if you don't skimp when you put them in. It takes more than you think to get an impressive show! If you plant them onsie-twosie they will make clumps, but they will always be scattered. Avoid the tulips with deer, they are candy - but if you do have a fenced area they cannot leap, crawl, or shove their snoots into many of the botanical varieties like the rock garden species sort spread well and so do Darwins and many Triumph. Squill of all sorts are an excellent naturalizer. I really love Siberian squill personally. Crocus spread well, may have flowers nibbled off with heavy deer pressure though. Most of the small bulbs will be fine really. Winter aconite, bluebells, lily-of-the-valley, star-of-bethlehem, snow-on-the-mountain, snowdrops, etc. Alliums are also a good pick, but do often take a long time to spread for the larger ones. Dahlias are fab, but need lifting in your climate. Be aware some of the things I have suggested may be invasive in your area, so you might want to be checking on that. Lily of the valley were impossible to remove once established when I lived in Ontario but oddly better behaved where I am in BC. (Probably because they hate the soil, but I'm okay with that)
