Isn't there a way to jump between conflicts in VSCode?

You are looking for these commands:

// merge-conflict.next
// merge-conflict.previous

So you can put something like this in your keybindings.json file:

{
    "key": "<your key here>",
    "command": "merge-conflict.next"
},

Search for "HEAD" and use F3 to move to next conflict and Shift+F3 for previous conflict !

VS Code used to provide keyboard shortcuts, but they were removed. You can restore them yourself though, just copy them from here: https://github.com/microsoft/vscode/commit/1de69f4d8d79f370d22f6720b54b7f4a140c60ca.
