I haven't seen a central repository for this, but there are some websites that collect seeds that are good for various purposes, which may include some of these. An internet search for Valheim seeds could help, but they will typically show the entire world.

I am currently playing on one that comes close to fitting this description. It isn't a single massive continent, but it is close. The spawn is on a large continent which can be further enlarged by building bridges across shallow channels to bring in more land masses. There is a smaller island that can be reached with a bridge off the north coast, and there is another large continent off to the east - a small island just off the east coast, a bit north of the spawn point, indicates a good place to build a bridge. It looks like there might be another crossing point a bit farther north. The continent, along with the other land masses I have discovered so far that can be reached with bridges, has enough iron and tar for a good start, but it will be necessary to sail or find more bridgeable crossings to find ample supplies. Also, not all bosses are on this continent, but all biomes up to the plains are present. It looks like there may be additional bridgeable crossing points that could add more land masses to the mix, so it could be a lot richer than I indicate. I'm still investigating. Even if none of the others pan out, this is a good seed for someone who doesn't like to sail a lot and who doesn't mind building a few long bridges. The seed is 3fgXajIW4r (note that the I is a capital I, not a lower case l or a 1) - it is my favorite so far, as it is perfect for what I like to do, which is build outposts all over the place and connect them with roads and bridges. I'm currently playing with a strict no portal rule, intending to rely on this transportation infrastructure instead.
