I summarized my local rec league's "No press" rule
here. Seems to work pretty well in most situations.
+1 to running-clock-except-for-last-X-minutes rules.
Possibly a "no-foul-out" rule (that would include an extra penalty like an automatic 2 points to the opponent for each foul a player commits after the 5th one).
No overtime (for Padgett). Alternatively, a "2-minute overtime, if still tied, first point wins" overtime.
One rec tournament I worked did a "substitutions mandatory, and only at 15, 10, and 5-minute marks in the half" rule (running time). I didn't like that one, because they literally wanted us to enforce it at exactly the 15, 10, and 5-minute mark, no matter what was going on on the court. (I got yelled at by the tournament director because I let an uncontested breakway start at 15:01 and end at 14:58 without stopping for substitution). Stupid, stupid rule.
