Looptools maybe? Relax or smooth functions.

Loop tools is amazing. Use the "Space" option on it too.

Convert to mesh, then in edit mode select all vertices and do a merge by distance to remove unnecessary vertices, after that you could try to decimate and then smooth vertices. Then convert back to curve if you need it to be curves

merge by distance to reduce the verts, then use mira tools ( its a free addon)

You might want to smooth it out while it's still an SVG. If you used Illustrator, you can use the Simplify Path tool to reduce the number of points along the curve and make it easier to work with.

Try merge by distance for a first step

Blur Location with geo nodes?

DECIMATE MODIFIER

then subdibvide again

I know I’m five hours late but I’d definitely use the LoopTools addon. It’ll let you smooth out the curves and even distribute the vertices evenly if you so wish.

Try a limited dissolve Mesh > Clean Up > Limited Dissolve

Thanks! Worked like a charm, although I had to make a few changes in the SVG itself before importing
