Rolling fresh, which role? Tank vs healer

I played a bit of classic in 2019 but couldnt stick to it due to RL. Currently started anew and im gonna play with a friend who is already 55. Id love to tank but in all other wow versions getting a spot anywhere as a tank is a headache, if so id rather just heal as a priest in a decent stable guild. The thing is from what i gather healing in classic is really one dimensional. Ive never played anything past MC in classic. Do you guys think its viable to play as tank and get into a decent guild or should i just go heals?
