Good afternoon Mike.
Selenium is not the best way to go to get consistent and pleasing brown tones with Ilford papers.
With Ilford Multigrade classic selenium delivers a warm purple tone.

On Ilford warmtone GLOSS paper it takes out the slightly green cast the paper sometimes shows and gives a muted brown tone:

However, MATTE warmtone FB tone horribly in selenium. Shadows tone to a peachy-orange while midtones and highlights remain almost unaffected. I have no examples to show as they all went in the bin.
I dabbled with Slavich paper, which toned just
beautifully in Selenium:

Adox MCC fibre didn't change much at all.
If I really want a brown tone on Ilford I use Fotospeed sepia
