I made an app you can use to find your perfect spawn seed or explore all 14 trillion chunks of your world for unique features. It's free, open source and runs locally - no internet required.
I haven't tested it with other versions other than the one I have (26.4 snapshot 2), I am sure people are going to have problems with it, especially with older ones, they seem to be very different.
Seed in the example is a spawn in a pale garden: -6294100580933879548
