It sounds like you mainly have a hard time dealing with laser camping. Try approaching with ice blocks. More specifically, dash forward -> full jump ice block can apply some pressure and give you an opportunity to get closer if you're pretty far away. Short hop ice block into a laser is also okay if you're kind of close since it lets you desynch the ICs and harass him with desynched ice blocks.
I personally like to get close to Falco and bait him into approaching me, partially since landing a solid hit through lasers can be tricky, and partially because lasers on their own aren't very threatening, so I don't have much to lose if the Falco is hesitant to approach. In the case that he really does just want to sit there and laser, try getting kind of close, shielding a laser, and approaching with a long wavedash OoS -> ftilt; that'll generally catch Falco out of hit next short hop before the laser comes out.
