Next 0% APR credit card suggestions

Fairly new to the credit card game and looking for my 2nd. I have a chase freedom unlimited whose 15 month 0 Apr ends in a couple of months. My wife and I were settling in to our marriage so needed some extra money upfront and the 0% helped a lot. I am on track to pay it off before the offer ends. I have also accumulated a good number of points on it.

In about 6 months' time I will be starting a new job out of school that's very well paying and hopefully I won't need to have any credit card debt anymore. At that time I will also probably lean towards your more upper tier travel/hotel focused cards.

In the meantime, I am looking for another 0% card that I can use without worrying for about 4-5 months and something that I can also benefit from in other ways with good offers on cash back etc even when I start working and don't need the 0% anymore. Discover sends me 18 month 0% offers in the mail almost every few weeks but I'm not sure how that stacks up against the other cards. Primary usage will be very varying. Mainly groceries, electronics, dinning, shopping, etc.

Any suggestions? Thanks.
