If your sketch plane for the triangle references the cylinder (using a mate connector on the cylinder would be a good way to ensure this if you cylinder isn't centered on one of the main planes) it should be fairly robust.
Here's a quick example of the split/move workflow (I used "realign" for the split mate connector but you could also rotate it 90deg along X if you cylinder is in a weird orientation)

Cut extrude (with a triangular sketch) or you could do a split face (with a sketch or just a mate connector) + moveface/rotate
And could you give some hint to a youtube or tutorial about option2? I'm quite new to the onshape (in fact I'm designing my 2nd part, before I had some minimal experience with freecad, so I'm not on level zero but ... almost there

True, you can use the split directly, not sure why I didn't show it like this...
Also when I know I am going to do something like this, I try to add line segment in a previous sketch if possible to make the mate connector selection quicker (i.e. without needing to rotate/re-align).
@eric_pesty Thanks, that was what I need!
@BenTaylor Could you please detail on the last step of your approach? I managed to have this (below) but it does not cut the shape.
