Fall deciduous care

Hello all, I'm just looking for a bit of clarification on what the appropriate procedure is for specifically Larch and Maple trees in the fall. As is the case with much of the information abt bonsai you can find online, there seems to either be some contention on the correct practices, or possibly just miscommunications on the various nuances that come with bonsai care schedules. Regardless, I seem to be coming up with different suggestions depending on where I look, and I would appreciate of y'alls thoughts on what is safe to do on these trees.

Too add some further context, the two trees I'm wondering about are a Japanese larch, and a trident maple. Both still in the development stage of bonsai. Throughout the summer growing season, I have carefully observed these trees and determined that the next best step would require somewhat intensive structural pruning, removal of large whorled/ unnecessary branches, and really starting to reign in the silhouetted of the trees.

My understanding of fall, (based on many hours of reading and horticultural research), has led me to understand that it is a transitional period for deciduous trees, where they shift from growing foliage mass, to growing more vascular cambium, hence why by the end of the season they will have shed all of their foliage. On top of this, it seems fall is the time where trees begin their shift into dormancy, by storing the last bits of photosynthesized energy and nutrients to both lower the temp at which the water in their systems will freeze and to sustain themselves until spring when they will release the stored energy in new buds. (Please feel free to correct if any of this seems off).

So then to my dilemma; On the one hand, I would assume fall is the perfcet time to be performing some major cuts, as the tree is now focused and grow vascular cambium, and any new cuts will get a heavy initial boost in healing. However, pruning also removes the foliage, which is still essential up until the last moments for the above-mentioned energy shifts. This would have me to assume that fall structural pruning is fine, and even ideal, as long as it is performed AFTER complete foliage drop? Conversely, I know that it is often said that structural pruning should be done late winter/early spring, just before new buds push. My question with that is; won't that force much of the stored energy from the roots to work on healing the cuts, thereby minimizing new bud formation? Is this just a necessary substitute? Furthermore, on the maple specifically, can't spring pruning cause excessive bleed, and unnecessary loss of again, those stored waters and sugars? (I'm not too sure on the bleed rate of larches, and if they are subject to a similar issue. Lastly, am I right to assume that just pruning at anytime in the winter is advised against, as it causes that loss of energy and nutrients as the tree tries to heal? Maybe I'm wrong about that

Ultimately, I wonder if it is simply a matter of the stage of development and what you are trying to accomplish with any particular action. Again I will clarify that these two trees are not really at the ramification stage, I simply want to start some initial styling with structural pruning. I'm sorry if this is way too much to read, but maybe this will be helpful advice for other people as well as we get into that fall season. And I know for me at least, learning abt and discussing the horticultural aspects of bonsai is SUPER fun, and I find it all incredibly fascinating learning about the cycles and systems of these trees, so along with any tips or advice (would be greatly appreciated), feel free to just open discussion on some cool stuff you've observed or learned through some of your own fall seasons

Thanks!
