CROSS

CROSS is a code-based digital signature scheme based on the restricted syndrome decoding problem.

Start with CROSS-RSDPG-128-BALANCED. It has enough security for most transactions and has the right tradeoff of size and speed.

FALCON

Fast-Fourier Lattice-based Compact Signatures over NTRU (Falcon) is a lattice-based digital signature scheme with small (for PQC) signatures and good performance. It is a bit complicated when it comes to signing so don't sign on devices that are susceptible to side-channel attacks.

Start with FALCON-512. It's small, it's fast, and provides more than enough security for most applications.

ML-DSA

ML-DSA (Module-lattice digital signature algorithm) is a lattice-based digital signature scheme based on the module learning with errors problem. It is standardized by NIST in FIPS 204.

Start with ML-DSA-44. PQC signatures are big so if security allows it, use the smallest one.

SLH-DSA

SLH-DSA (stateless hash-based digital signature algorithm) is a stateless hash-based digital signature scheme based on the difficulty of finding preimages of hash functions. It is standardized by NIST in FIPS 205.

Start with SLH-DSA-SHA2-128s. When a scheme is as conservative but slow as this scheme you might as well use the smallest signature.
