Silver tier

I need to book LHR to LAX and I just noticed I am now at silver tier member.
Does that mean I can fly economy light (cabin bag only), but still take a free checked bag and get priority check in and boarding through my silver benefits?
It’s coming to £500 return trip which seems reasonable given some of the perks of silver.
I did consider flying back in upper class on the night flight but the app won’t give me this option unless I upgrade to economy classic on the inbound, is this by design?
Thanks
