Only one other country in the world (Denmark) has a debt ceiling, and that ceiling is over three times the actual public debt; it is a formality and was recently raised significantly, which removes it from practical budgeting considerations. A debt ceiling is an unneeded complication. To limit debt, the Congress should not purchase goods/services that it can't or won't pay for. By the Constitution, spending bills must originate in the House. It's that simple. It's the politics that are tough.
