Hey Danny, it’s not so much that they are ambitious in Blender, IMO, it’s the time involved.
Anything you do in Blender is going to require a render; if you want to make an animation change - re-render; change the text of a GUI graphic, or a change in how bright your shield lights up due to a laser hit - re-render!
It’s way easier to tweak a 2D effect in post in your compositor than it is in your DCC, or digital content creation app.
Even though at times I have a love / hate relationship with HitFilm, I’d def rather do my lasers and explosion effects using HF, than in Blender - I’m not even sure how I’d put together a scene with “laser beams” flashing around and hitting various moving targets in Blender??
(Transparent meshes w/alpha images and MOV files displaying stock flash images at contact points? Stretched out, emission lit cylinders for the laser beams?? - Again something way easier done in post!)
Now water sims, asteroid breakups, scene destruction w/buildings crumbling, perhaps tornado / hurricane effects, and in the odd case, hero objects exploding w/smoke & particle effects (Houdini Indie, or targeted Blender add-ons), I would consider doing within the DCC.
And even the buildings crumbling, or asteroid breakups can be isolated into their own scenes; video clips rendered, and swapped in at the right points in your movie editing timeline; want to add additional hero asteroid breakups or tweak the building crumble, just modify those isolated scenes and re-render just those portions…
Back in the day I was using AfterFX, (I refuse to even reinstall my AfterFX CS6 now, cause I know pretty soon it won’t be usable, and I’m not interested in $Adobe tool$ at this point in time!)
So for me today, it’s HitFilm and Davinci Resolve / Fusion. (There are rumors that Andrew Kramer may be porting over his AfterFX plugin Element 3D plugin to HitFilm and I CAN’T WAIT for that to happen!
This is why most compositor apps now allow you to load in 3D models, camera animations etc., from your DCC. HitFilm was just recently endowed with Foundry’s camera tracker tools which was a surprise, and a hella great addition!
So I’d say, even if just for ideas on what can be done, install the free version of HitFilm and follow, some of the laser, explosion, and other effect tutorials they have on YT.
At that point you’ll mostly be modeling / texturing your Hero objects / props, and doing your effects and perhaps even spaceship model anims in HF on the editor timeline - should be way easier (and faster) that way…
Whatever you do, just make sure you’re having fun - enjoy!
