Fathom E+ 2 2019 29er fork and tire upgrades

[omnimodeus]

So i have stock forks SR Suntour XCR32 LO 29" 100mm travel, Tapered 1½ - 1⅛" steerer, lockout and stock tires Maxxis Ardent 29x2.4", EXO, 60 TPI
and i would upgrade both for more agressive ride. I would like to have 120mm forks and thicker tires. Any suggestions?

Wallet friendly, nothing too extreme.

I climb often on steepy hills, rarely jump.

Im total newbie for mechanics and choosing compactible parts so any help will be appreciated.

Thank you all for letting me in

My buddies Focus Jam2 has a Rockshox Recon. This fork has performed well for alot of trail miles. It's not super stiff, but certainly adequate for mere mortals. As an entry level performance fork, I like it.

Any specific Recon model?
I just found used but in excellent condition, Recon Silver 2020 for 220$. Should i go for that?

I believe a Recon RL was spec'd on the Jam2 Ltd.

I found this offer (used):
Fox 32 Evolution CTD Float 120 mm, CTD handle on fork, steerer lenght 17.9 cm, tappered steerer, thru axle 15x100 for 220$

On fathom spec it says:

• Giant eTracker Sport, [F] 9mm QR [R] 141mm QR, e-bike optimized

Should this fork fit on my bike? Sorry for newbie question?
