Id say do it.
We were in he same situation 3 years ago and we’re both happy we decided to spend the extra on ours (We went for walnut)
I think the worktops were about £2.5k, the kitchen needed to be fitted first and then a couple of guys came round and made a custom fit worktop out of chipboard. 2 weeks later they came back to fit the worktop.
TBH we have neglected it and it still looks great, we should really seal it every 6 months but have only done it twice since it was fitted. I know it will easily outlast the kitchen as it can be stripped back down and re-sealed to make it look brand new.
We also considered granite, I really like granite in the right kitchen. Wood was better suited to our 1860’s cottage IMO.
