Description
Since JuliaLang/julia#222 , fill +/- loses support for most structured arrays.
julia> s=Symmetric(rand(3,3))
3×3 Symmetric{Float64, Matrix{Float64}}:
0.110199 0.379641 0.536482
0.379641 0.518226 0.384931
0.536482 0.384931 0.955319
julia> s+Zeros(3,3)
3×3 Matrix{Float64}:
0.110199 0.379641 0.536482
0.379641 0.518226 0.384931
0.536482 0.384931 0.955319
It's not practical to list the types since ToeplitzMatrices, LazyArrays, StaticArrays, etc., are not dependencies. This could be solved in Julia 1.9 using package extensions.

Research direction
Start by reading JuliaLang/julia#222 and the current FillArrays behavior for fill +/- with structured arrays. Investigate how Julia 1.9 package extensions could support types from packages such as ToeplitzMatrices, LazyArrays, and StaticArrays without adding dependencies. Done means structured array types retain support for these operations.
