Questions on routing NM runs

I need to run some NM across a basement in a direction perpendicular to the joists. I have very old joists and would like to avoid boring if possible.

I am able to run parallel through the bays until it's time to cut over and I can do one of two things:

1) go around and against a carrying beam in the middle of the house. This will cost more wire overall and it is already pretty packed with other wiring.

2) Go around the other edge of the joists against the exterior wall over the sill plate. It is a masonry block foundation and there is a wooden sill and a couple of angle iron lintels, It is tight but there is room. What I do not know is whether this is permissible or not. It will also be harder to secure it unless I pull a little loop back and tack it to the face of the joists at the ends.

TY for any info!

The easiest thing to do is buy some plywood strips and nail them perpendicular to the joists, creating a running board. Then you can staple the NM to that.
