Travel systems recommendations!

I have been researching so many different strollers and car seats, it’s become quite overwhelming. I know I want to stick with chicco or Graco for my brand! I’m just super unsure if I should go with a stroller that attaches with a car seat like the graco fast action SE travel system or if I want to go with graco 4Ever car seat.. There are too many options out there and this is my first time! I preferably would like to get things I can get good use out of.
