I use a decent sized laminated bamboo cutting board like the one pictured below from Ikea APTITLIG $12.99 USD but actually use the thin DRÄLLA boards also Ikea pictured below $1.99 USD for a two pack (also Ikea) atop it. I like these for a couple of reasons-
1. Laminated Bamboo cutting boards seem hard on knives, at least in my experience, perhaps due to silicon content inherent in grasses?
2. It is a whole lot easier to sanitize these than any kind of wood block & at that price its easy peasy to have 6 or 8 around - they wear well & as they start to get a bit careworn we just take them to Venezia and leave them behind in the rental apartment we use there most years.
3. The flexibility of the thin boards is also a nice feature to have.
4. The red/green colours are helpful to remind one which boards require hardcore sanitizing & which don't.
Obligatory disclaimer - no financial interest just a satisfied user of these products blah blah blah.
