You don't need a preset to start a project. PP will assume that the sequence settings will follow the clip for starters. You can override it but there is little reason to do that in the beginning. Just drag your first clip to the timeline, rename the resulting sequence (the default will be the clip file name which is likely not the most helpful). Edit the sequence as you like. If you have a slower machine that doesn't render 4K all that fast you can set the preview file size to be smaller.
You CAN change the sequence settings but I never do. I leave it on 'custom'. You then export the file in the appropriate format.
Is that what you were asking?
