If you are looking for a seed with tons of trees, stone, and diamonds you will want to use a dungeon/ cave seed. The reason for this is because cave systems, and dungeons contain more resources usually. A good tip to finding diamonds is if you are underground and come across lava there usually is diamonds near the lava around the same level as well so do not dig under the lava.
A list of Dungeon/ cave system seeds you might want to try out.
These are just some of the many seeds out there. If you want a lot of trees just go above ground, if you want a lot of stone you will find plenty of it finding diamonds.
I hope this answers your question, and have a nice day.
