I need a good alg for this center swap case

I have already used two solvers(ksolve++ and OMNIA OBTORQUEBANTUR 5x5x5) to find few algs, but I can't get that many alts, as bigcube solvers are slow. Like OMNIA(5x5 solver by Ed Trice) took 4 hours to produce a unfingertrickable alg. I asked the community on BSG on May 16, 2021 and got interesting suggestions.

3 algs I have received till now are:
[2U m': U2] [2D' m': U2]
U2 2R' U2 m U2 m U2 (2L' 2R') U2 m' U2 m' U2 2L' U2
2R s R2 s' 2R' 2L' s R2 s' 2L

These algs are good!
 
These are LONG, but they are different (no inner slice turns + short repeated sequence).
l' (R U R' U)5 l r (R U R' U)5 r' Or l' (R U' R' U')5 l r (R U' R' U')5 r'

And you can conjugate this opposite center swap r2 (m2 U2 F2 U2)2 r2 with the classic non-pure adj center swap (in beginner 4x4x4 tutorials):
[l U2 l' r' U2 r': (m2 U2 F2 U2)2]

(I'm not a speedsolver, nor have I ever did a BLD solve, so maybe these can be adjusted to be better.)
Thanks for sharing more options!
 
Np.

And you can conjugate one of these (all move-optimal in STM)
U2 B2 D2 M D2 B2 U2 M'
U2 M U2 B2 D2 M' D2 B2
F2 D2 B2 M' B2 D2 F2 M
F2 M' F2 D2 B2 M B2 D2
D2 F2 M' F2 D2 B2 M B2
D2 B2 U2 M U2 B2 D2 M'
D2 B2 M' B2 D2 F2 M F2
D2 M D2 B2 U2 M' U2 B2
B2 U2 M U2 B2 D2 M' D2
B2 D2 F2 M' F2 D2 B2 M
B2 D2 M D2 B2 U2 M' U2
B2 M' B2 D2 F2 M F2 D2
M D2 B2 U2 M' U2 B2 D2
M U2 B2 D2 M' D2 B2 U2
M' B2 D2 F2 M F2 D2 B2
M' F2 D2 B2 M B2 D2 F2

For example, [u m' u2 m z': [m', F2 U2 B2]].

M U2 B2 D2 M' D2 B2 U2
M' B2 D2 F2 M F2 D2 B2
M' F2 D2 B2 M B2 D2 F2

For example, [u m' u2 m z': [m', F2 U2 B2]].
Hmmmm the main factor is that the algs should be fingertrickable and fast to execute as well.
Regripless and rotationless as well

2R s R2 s' 2R' 2L' s R2 s' 2L

These algs are good!
Second one is probably the best, regripless and fast (I can execute it in about 3 secs) but the third one has lots of potential if we find the right fingertricks
