For my 2 cents, i would also say that it's a nice shape already now that 1 top of the main tip would let those side branches crown out real nicely and give it a good even canopy.
​​​​​​As for trimming the rest, me personally i like to trim a fair bit so i would snip off most of the fan leaves coming off the main stem from the bottom up, just leaving top 2 sets, so as to improve air circulation & light penetration. And then at bottom of stem end upwards I'd also snip off any smaller side branches that don't currently reach/stretch over the sides of the pot - probably just the bottom 1 or 2 branches will cover it, and basically leave the bigger, similar length branches that will come up good together as part of the crown. If you don't fancy topping tho, then i agree just light trim is best, plus it'll possibly stretch up a fair bit in flowering which will open up internodal distance for air & light anyway.
If you're not too sure with trimming, best idea is go lightly as can always take more off but can never put it back on again! Also, I'd recommend doing it early after lights come on rather than doing it just before lights go off for night, as gives them better recovery position.
