For survivability you have passive/operator/kinetic plating which is plenty, so for survival mods I would only recommend [Rolling Guard] if you feel like you really need it. Kinetic plating maxes at 100% ability strength and is the only ability that really wants strength so there's not much reason to mod it other than helminth/low level nuke. Balance the rest of the stats however you like.
If you don't know how to nuke: Charge battery to 100% > (blast sunder crowd for full strip so heat procs can do more) > spam heat sunder as much as desired (don't let the heat proc disappear) > use cold sunder to now proc blast sunder > blast sunder will apply dmg that stacks with the amount of heat sunders you stacked(, and apply dmg after the full strip to any new enemies that weren't previously stripped).
Replace Kinetic Plating
Last slot is for fleeting expertise/augur reach/equilibrium/ect.
For relic runs: you could slot preparation in exilus, and slot some ability strength since enemies would be weak enough it can make a difference.
Aura, exilus, and arcanes are up to user.
The Warframe Community Discord is a great place for build advice, and along with the wiki are great places to to learn.
