these have been confused in photos before, though the differences are obvious when you see them for real
They're not wildly invasive or difficult to remove. Handy for dry shade where not much else thrives. It wouldn't be at the top of my list for a very small garden.
Can you move it out of the way or is there no safe place?

macrorrhizum for me
Probably Geranium sanguineum or one of its cultivars
I think Geranium macrorrhizum. From smell, stage of growth right now and general appearance
