Greetings Dynobot,
There is really not much I can add about Blender 2.9x except to say that the Biggest change in everyones workflow in the last decade has been Realtime viewport rendering & Rendering in general.
Since switching from Maxon C4D to Blender completely, for both content creation and final animation rendering , back in April this year,
I could never go back to any 3DCC software that did not offer realtime or very rear realtime viewport performance.
For general look Dev & TD/lighting work, Blenders EEVEE is quite the treat after so many years struggling with C4D’s Bloody awful veiwport.
I am currently working on an animated web series based on the Popular videogame franchise “HALO” from 343 Industries.
and creating all of the content in Blender including the custom clothing& armors for my Iclone/CC3 Avatars
and importing my animated Characters from Reallusion Iclone/CC3
back to Blender for rendering
I will be doing all of my final renders with EEVEE.
I would also strongly …Strongly!! urge you to invest in the Hardops& box cutter add-ons even if your modeling passion is sculpting.
Also be sure to get the free SSGI plugin for EEVEE from Github
(or perhaps Gumroad??)
Essentially it enables realtime (screen space) Global Illumination for EEVEE, giving Emmissive materials the ability to act as light sources in EEVEE the way they do in path tracers.
On the matter of free or low cost companion software for Blender
You should have a look at Krita as well.( free)
They have done a right proper job at ripping off Adobe photoshop
with the latest release ( in a good ,flattering way)
and it is a much more “polished” tool than GIMP IMHO
Also Krita ( I have found) is the only free 2D editor than can output SVG files that Blender can recognize /import for extruding 3D models from vector profiles.
Also I now use the Free version of Davinci Resolve 16 from Black Magic Design,
Not only does it have an excellent nonlinear editor with non destructive adjustment layers and color grading tools, but a proper node based compositor( Fusion)
with many open FX plugins/ effects.
and a powerful ,feature rich sound editor called “fairlight”
I have found Davinci resolve a perfectly suitable finishing/delivery replacement for my aged Final Cut Pro and After Effects CS since leaving the Mac OS platform for good after finishing a very long term 93 minute animated film project back in April.
Cheers.
