Can't go wrong with ginger tea in my opinion. Pretty easy to make yourself as well. If you want something sharp and fruity look for blackberry or redcurrant. Melon teas can be pretty good too.
As for real tea I'd recommend greens since they're healthier but I've never tried bagged green tea if you're looking to avoid proper brewing. Sencha is distinctly grassy so it might be a miss but it's a decent starting spot.
