~3 miles, 5–8 min. Two app-based options:
All-contactless isn't possible end-to-end: Sandy is outside the contactless zone (boundary ~Stevenage), so you tap only to Farringdon and buy a separate Thameslink ticket onward.
An Advance ticket is valid only on the exact train you book. Miss the 10:11 because immigration or your bag runs slow, and the ticket is dead — you can't use it on the next train and must buy a fresh one. Off-Peak is valid on any off-peak train that day.
When can you buy the Advance fare — and when does it close? "Advance" is a ticket type with a limited quota per train, not a "how far ahead" rule — buying the day before still counts (cheapest tiers sell out first, so earlier = cheaper). The cutoff varies by operator; GTR (Thameslink's group) closes Advance sales at 18:00 the day before travel on its Southern brand, so treat Thameslink the same.
Bottom line: if you want the ~£14 Advance, lock it in by the evening of 16 June — you likely can't grab it on the Elizabeth line that morning. For an unpredictable arrival, the flexible Off-Peak Single (~£20) is the safer buy; the Advance only saves ~£6–9.
