Roman lettering might be very appropriate, but is very difficult to get square, even and regular looking. Practice a lot.
With the Roman family lettering, I do the cuts lightly at first, and am able to re-cut longer or wider as I see I need to correct. The serifs come last, and slight height adjustments can be made while cutting these, as well as the spacing between letters can be fudged a little bit with longer/shorter serifs.
