Most plugins are compatible for both Vim and Neovim.
I'm not aware of any popular plugins that is Vim compatible and not Neovim compatible.
Neovim has a more rich Lua binding and some plugins make use of that functionality making them not compatible with Vim.
You'll find on the home page of the plugin the requirements for Neovim only.
Some examples are:
The Neovim tag on VimAwesome gives you a hint that the plugin is for Neovim only (VimAwesome contains both Vim and Neovim only plugins).

The NeovimCraft seems to focus on Neovim only plugins but some plugins of the list are also compatible with Vim (e.g. barbar or markdowns-preview)
