That sounds reasonable to me. Ramping back up after a significant layoff is not a science, it really depends on the individual.
I also start with 135 squat, then can add pretty quickly. But I start there to ensure my form and balance are on point. The 195 DL sounds about where I start up at also.
I don't think you are being too conservative, but others may disagree.
The most important part about coming back after a layoff? The mental game. Those starting weights for me lets me think "hey, I am back".
Load the bar too quickly and it seems discouraging.
