In that park I would look for a good contact hitter, high hit rate, low walk with some speed. Staying in the theme of good, to relatively good fielding coupled with the amount of money it appears you're willing to spend, I would narrow my choices down to:
1929 Lew Fonseca (685 PA/162, 44 doubles, 15 triples, 23 K's and 50 bb) with 78 speed, 24 1B/100#, 2 3B/100#, .959 contact rate and .378 hit rate, A-/A- fielding and a .426 OBP
1921 George Sisler, (668 PA/162, 38 2b, 18 triples, 27 k's and 34 BB, 89 speed, 35-11 SB/CS, 23 iB#, 2 3b#, .954 contact and .376 hit rates, 127 AVG+, $6.72m price tag, B/C fielding, .411 OBP
1976 Carew, (687 PA, 29 2b, 12 3b, 52 k's and 67 Bb, 92 speed, 49-22 SB/CS, 129 AVG+, 24 ib/100#, 2 3b/100#, .914/.351 contact/hit rates and a pretty good value at just a hair under $6mm. .395 OBP.
I realize that the 1920s guys above have RL 1b/100 and 3b/100s are higher than their # figures, but all in all, they should still perform well without tiring.
