I do delegations from peakd.com’s wallet page. There’s a “Delegate” button as well as a little magnifying glass icon that leads you to a page showing which accounts you already delegate to or receive delegations from. The “to whom” question is personal preference of course. Bid bots have all but died but if you’re looking for a return, you can get Hive payouts from various services like @tipu, @ocdb, @hodlcommunity and such or LEO payouts from delegating to @leo.voter
