What Coil Springs to get for the daily driver?

I have a 2010 V6 4WD with 300K miles. I don't think the coil springs have ever been replaced and I am noticing some issues. I believe the shocks are fine for now. I drive 80% on the highway and county roads with 20% being off-road. I do not care for extra lift or any aesthetic elements. I just want something affordable, comfortable, and compatible for the vehicle.

What would you recommend to look into and what should I stay away from?
If I do have to get some new shocks in the future I would either get the 4600 or 5100, I have just read so many people recommending those shocks, would that make any difference on the coil spring decision making process?

Thank you for your time and reliable assistance taco forum o7
