Suggestions for filling out a fleet's destroyer and frigate options :D

Hey folks!

I'm currently coming up with a hightech fleet idea for a stream I'm thinking of doing for stellaris, and I'm drawn to the new ship, the Anubis. I know for certain I want it to be fighter heavy and high/mid tech, and I also know that I want the Astral and the Anubis slotted as the capital and the cruiser for the fleet doctrinal. I'm not going for Meta so I'm set on those <3

The thing that's up in the air right now is the destroyer and frigate slot. At first I thought the scarab, as thematically it would be fun to have both it AND the anubis, but then I shifted to the monitor so I could have some ships that could soak up firepower on the front (as the other two large ships are carriers/support vessels). Same thought for the destroyer: Kind of want something that do frontline fighting.

One more stipulation is that I don't want to go into lowtech ships: purely looking for midtech/hightech vessels.

If anyone has some suggestions, I'd love to hear em! :D
