Fit should be cap stable and no cargohold is wasted for cap charges. If you learn how to sig tank and overheat your shield hardener from time to time you are good with tanking. 1 mn AB low speed is no issue here since you can project at any necessary range. With few implants (ee-603, for example, if you lack CPU) you can make fit less expensive.
Just note, that your DPS will still be much lower, than that of larger ships. Which will hurt isk/time efficiency. But you can warp away in 3 seconds, which is good for GTFO situations…
Any rocket fit will lack the range.
Confessor is an awesome ship for C1 but you should realize, that cruisers will run 45 km away, so you will have to wait to apply your confessor maximum damage that far. Or use 55 km range light missiles as I suggest in jackdaw.

That fit will also hit 45 km but only with Aurora charges. That means - less DPS, than a jackdaw. But Gleam charges at 6 km range will give you almost twice DPS vs jackdaw. So you will kill frigates much faster, but ship is slower, less agile and you will have less tank in sharpshooter mode…
