I'm afraid that Neopan had a very distinct look that is hard to get.
Maybe try some T-max or Delta, but even then it's doing to be quite different.
Tri-X and HP5+ definitely won't give you the look you're after, so I wouldn't bother.
There is that website called
https://filmtypes.com/ which has samples of many B&W emulsions. You should check it out.
Edit: I was just looking at the site. Check-out Kentmere 400. You'll probably like it.
