| I want to test out some mechanisms I have ideas for with Technic pieces, but
I don't have the pieces I need on hand. Studio lets you rotate and move pieces,
but it doesn't seem to really work with full systems.
I was wondering if there were any ways that I could simulate/test my ideas virtually
instead of needing to order all of the parts before knowing whether it works
or not - Any help is appreciated!

There was SR3D but I don't know if this still works...
See here:

Apart this, Fusion 360 or such generic parametric CADs, but then it'll REALLY
be a huuuuuuuuuge task.

LDD (Lego Digital Designer) was pretty good for simple technic mechanisms (and
other things that Studio is rubbish with, like flexible parts) IIRC. It's
old and very outdated, but there are some unofficial mods that you can add, so
you can update the partlist significantly, but these probably aren't necessary
for your needs.

Functionnal: Only hinges, never gears. And it sometimes crashed when you tried
to use a hinge.
Building: It had hinge-connect: to automatically hinge multiple connections to
make triangles (or polygons).
It had a tendency to also move the ends / anchors, so that you got your triangle
but it was not sitting right any more.
It also tended to crash when doing that.

YMMV. It had bugs with some flexible parts too.
It’s called the ‘Good Old Days’ syndrome

If you’re on Windows 10/11, it’ll be necessary to look into the Eurobricks forum
though because the last version (4.3.12) installs but doesn’t work and the previous
version (4.3.11) works but needs some tricks to be installed.

Gears worked in LDD - https://www.youtube.com/watch?v=iQ5jiikMJoQ
and connecting pins, axles, Technic bricks and liftarms was easier (IIRC). But
yeah, it was a looooong while back, so I might indeed be wearing a shade of pink
in my spectacles.
As for flexible things - I didn't test too many options BITD TBH, but what
I needed worked and worked well. I don't recall having crashes, but I probably
didn't strain LDD too hard. It certainly never stuttered or glitched like
Studio, however I do prefer Studio to LDD; especially the colours - I will never,
ever get used to Lego's naming convention for the colours (which always looked
awful in LDD too).

Not available in the free version. (Clearly shown by the comments under the
video.)
It’s either the Pro version, a fake, or a (very complicated) trick made by adding
hidden parts and universal joints.

Sort of. It had fewer possibilities for placement, so it made it easier.

I do.

I didn’t. Just flexing a hose or two. I learned to save my work before doing
it
Also, I can’t find the posts on Eurobricks right now but I remember that, in
the last couple updates, it had weird glitches with some 3mm hoses: triangles
all over the place when you flexed them.

Well, it certainly didn’t like big models. Two modulars together was hard for
it. (And that was the 1000 parts modulars of the time, not the last 4000 parts
ones )
