Buying my first grill in a few weeks as a graduation present to myself and hoping to tap into the collective FT wisdom for some advice.

I'm really leaning towards the Weber Spirit E-310 and Lowe's is offering free delivery and installation right now on grills $498 and up (which the Spirit qualifies for). Plus I figure I'll buy a Lowe's gift card from Kroger and get 5x on my Chase Freedom and then go through a portal for another 2-3x to get a nice double dip.

What other key elements should I look for as a first time grill buyer? Thermometer fork? Grill cover? Brush for cleaning? Anything else?

I'm okay with paying a bit more for the grill for quality (which is why I'm looking at the Weber) but for everything else definitely looking for value purchases, don't need the name brand. Thanks in advance!

Mods: I saw an old grilling thread but it was 6 years old so I'm starting a new one feel free to merge if you see fit (or move to OMNI if appropriate)
