To me, the conventional deadlift (feet closer together, hands outside knees) is the most advanced variation of the deadlift and likely NOT the best starting point for most lifters.

Whether it's someone's anatomy (short arms and/or long torso) or mobility deficits (hip flexion ROM, thoracic spine extension, or even ankle dorsiflexion) the conventional style deadlift might not be a great choice... for now.

A sumo-style deadlift (wider stance, hands inside the knees) may be the better option. It allows for a more upright torso, decreasing shearing forces on the spine, which can make things infinitely friendlier.

Stop being a slave to your ego and realize you don't have to pull conventional all the time (or ever).
