Well......you asked for opinions. What you will get are just that, opinions. They will generally be worth exactly what they cost.
I was off a lot longer than you. I found that riding, all kinds of riding was good. You don't say, but if you are a competition rider do what your trainer says. If a "hobby" rider then while paying attention to form put on miles, lots and lots of miles.
Mix that up with a competent weight program and in a wee while you'll be back in top form.
But be careful not to push too hard. Or, you risk joining the ranks of the permanently injured. From experience, mine and people around me, I can say that unless you have a full time rehab staff and spend all, I mean All, of your time on rehab the words Quickly and Full Recovery do not belong in the same paragraph.
